Re: [hugin-ptx] Hugin 2022.0 Black blotches on final stitches

[Luís Henrique Camargo Quiroz]

   Hi!

   One idea: if you can, try cropping (by use of exclusion masks) and
diminishing/changing  the superposition among adjacent images. At least
where you saw problems.

   In a few days I'll be able to use Hugin again, I needed to put my
panoramas on hold because of other activities. But it was really a while
without such kind of blotches in my last panos.

  all the best,

   Luís Henrique

Re: [hugin-ptx] Stitch Panorama Without Blending Exposure?

[Luís Henrique Camargo Quiroz]

   Hi,
   Maybe  "--save-masks --visualize" as extra options in the enblend call
you will have what you want.
   The manual (see https://enblend.sourceforge.net/) explains the colors in
the visualization image

Re: [hugin-ptx] Re: Mac builds of Hugin

[Luís Henrique Camargo Quiroz]

   Hi,

   Just to say that for beginners it may seem confusing how to use git or
mercurial, start a new branch, etc. I think that anything done so far was
in the best intention to help, especially for those with Macs.
   I don't think that Tomas meant to be heavy on negativity, nor with
intent of discouraging anyone, but an alert to be double cautious, because
of the problems we can create in git/mercurial/others -- I myself have
never found a concise and perfectly understandable guide on how to use
these programs. And while adventuring to fix software from others made many
mistakes too, because there were lots of things I was ignorant about. I
ever had to spend time, months maybe, until I knew what was the right thing
to do.

   nice weekend!

Re: [hugin-ptx] sticth picture using hugin

[Luís Henrique Camargo Quiroz]

   Hi!

   Have you seen the tutorials?
https://hugin.sourceforge.io/tutorials/index.shtml Some of them are done
with older versions of Hugin, however they all show you how you can use the
program.
   Also the Panotools tutorials at https://wiki.panotools.org/Tutorials
will show you how to correctly take the photos for a panorama and even some
more advanced techniques.

Re: [hugin-ptx] Re: Repeated failed stitching

[Luís Henrique Camargo Quiroz]

Hi Alex,

The OMP messages have nothing to do with your images nor the way you
try to stitch them, for sure. They are related to OpenMP, a library for
parallel processing in the CPU (and also GPU) cores. They show us that the
program (enblend, in this case) needs some code updates because OpenMP
evolved and the program uses some function calls that are now obsolete.
About the Dijkstra optimizer and seam-line end point outside of
cost-image, I sometimes -- I think less than before, maybe I perfected my
shooting technique? -- get them. When that happens, enblend may fail and
the output image is automatically erased... In this case, use of masks or
another order of the photos may help to reach a successful stitching.

   I have not yet stitched any true mosaic, however I use mosaic mode for
my nadir images and in this case it works very well.

   Good luck!

   Luís Henrique

Re: [hugin-ptx] Re-arrange image order to fix "blackout" sections

[Luís Henrique Camargo Quiroz]

   Hi Rich,

   Some ideas that can help:
   1 - use enblend with the option
--primary-seam-generator=nearest-feature-transform, this maybe is the best
solution in general,
   2 - see if you can modify the amount of superposition between images
(use masks to "cut" and shape excess superposition)
   3 - maybe enblend with --pre-assemble (can be used with solution 1) can

   Now I rarely face this problem, I hope these ideas help you too!

   Thanks Harry!

   I have some photos (not panoramas) for exposure stacking and will try
PyImageFuser with them, it arrived just in time!

Re: [hugin-ptx] Enblend cannot find mapped files

   Hi Dries,
   Just a guess here: maybe the (blank) spaces in the filenames are to
blame in this case. It is the same OS, but maybe some configuration is not

Re: [hugin-ptx] Stop enblend from removing result

[Luís Henrique Camargo Quiroz]

   I have also  the feeling that very intricate masks, e. g. to remove
tripod shadows with exclude masks, used to allow small patches of a "no
shadow photo" (in some cases more than one photo), can lead to an invalid
auto-destroyed result.
   In that cases only redoing the masks and retrying some times gave me a
result. Or I gave up and post-edited the shadow later.

Re: [hugin-ptx] Re: Adding zenith shot

[Luís Henrique Camargo Quiroz]

   Hi,

   Have you seen https://panospace.wordpress.com/2008/03/18/edit-the-nadir/
and other tutorials at
https://wiki.panotools.org/Tutorials#Zenith_and_Nadir_retouching? They may
give some clues.

   What I do: I just create control points connecting the nadir with other
'pointing down' images, then I optimize. This is all done in Hugin. If the
nadir shot is good, without (noticeable) parallax, the result will be good
enough; in a few cases minor retouches will make it be 'magically perfect'.
You know, the tripod disappears, and people will wonder how you made that
happen...

Re: [hugin-ptx] Stitcher parameters affect Optimizer result?

[Luís Henrique Camargo Quiroz]

  Hi John!

  the cause is the final output:
  -- a.pto has the default size of 3000x1500 pixels, as you see in the 3rd
line of the project: p f2 w3000 h1500 v360  k4 E9.50383 R0 n"TIFF_m c:LZW
r:CROP"
  -- b.pto has probably the maximal output: p f2 w21686 h8552 v71  k4
E9.50383 R0 n"TIFF_m c:LZW r:CROP"
  Once I had your same doubts about "sudden" variations in the errors, then
I realized the error depends of the output size. Now I ever use the default
3000x1500 when I take notes of my results while optimizing my panoramas.

  I am glad you are trying to improve Hugin. I don't know (yet?) how to
program in C++   :(

  regards,

   Luís Henrique

Re: [hugin-ptx] Re: Removing magnifier hiding timer etc. from CPImageCtrl.cpp

[Luís Henrique Camargo Quiroz]

   John just told us about another annoyance that I, while adding manually
my control points, see all the time. I put the text in bold, in his first
paragraph below.
   I even tried, in vain, to immobilize the mouse -- with both hands! --
before releasing the button to create a CP, however the carefully chosen
position moves and then I have to use the arrow keys to reposition it where
intended. I think the movement is always to the right, maybe a little up,
and it seems to be by a fixed amount.

Re: [hugin-ptx] Removing magnifier hiding timer etc. from CPImageCtrl.cpp

[Luís Henrique Camargo Quiroz]

 Hi John!

 I have never really used 200% magnification, and the lack of the
magnifier in it was the culprit. Even if the magnification were low, an
important feature is the "high contrast" the magnifier provides.
 What about keeping the views at 200% and just the magnifier (or a
bigger one) at the intended 400 and 800%? So the left and right views would
show a bigger field of view.  I like to use manual control points, so the
CPs are not on wrong places, never, so the stitched pano will have no great
flaws... for my use case I like a big view, it helps to understand where I
am moving to mouse in the scene. I fear that at 400 or 800% the view will
show very few from the broader scene.

 I thank you in advance for your efforts and ideas for a better Hugin.
Wish you good work and luck!

sincerely,

Luís Henrique

Re: [hugin-ptx] Re: How to export panos to Google Maps?

[Luís Henrique Camargo Quiroz]

Hi Carlo!

Yes, I zoomed out in the map view (after I closed the panorama) to see
where that place was, and could not go back to the pano, the *blue dot *is
yet missing...

Don't worry at all! Is this panorama still very fresh in Google Maps,
am I right? I bet yes!  The blue circle indicator will appear some days
after you uploaded the panorama. Even now, when you hover the mouse over
the right spot, the panorama will appear, maybe you have already seen this
behavior.

   "happy panoraming",

   Luís Henrique

   Hi David,
   No idea about  this horizontal line detector. Perhaps a mistake? This is

   A good new year!

Re: [hugin-ptx] Nona is producing strange colors

[Luís Henrique Camargo Quiroz]

  Hi Stephan!

   Once I had much worse strange color (mainly red dots if I recall well)
spread across many photos. It was solved when I used enblend with
--blend-colorspace=IDENTITY as parameter.
   In your second photo there are no "red wood" colors on the floor, but a
darker zone at right. Is it  shadow or a problem?

   regards,

   Luís Henrique

   Hi John,

   Bruno uses ptodummy to create images for the pto file. It is just one of
the very useful tools from Panotools-Script:

   I will just intall those tools in a new system now ;)

Re: [hugin-ptx] Re: Stitching map screenshots

[Luís Henrique Camargo Quiroz]

   Hi Marco,
   If you change the default 'panorama' (the stitched image from the map
components) size from 3000 to any other value the error will change, as it
is based on this 3000 pixels size. Don't fear this effect, it won't change
your result.
   If your partial maps are screenshots, why do you think there will be
exposure variations from one image to another? Did you change the screen
brightness, or used more than one single computer?

   If you adapt the  flat scanned images tutorial (
http://hugin.sourceforge.net/tutorials/scans/) to your case -- e.g. roll
probably is 0 for all images -- you are in the right direction :)

   Good luck!

   Luís Henrique

Re: [hugin-ptx] Re: lux - FOSS multiplatform image and panorama viewer

[Luís Henrique Camargo Quiroz]

HI,

   For information, I just installed lux-1.0.9b-amd64.deb (via dpkg -i) in
Debian 12 (testing) and it went flawlessly.

  As a side note, I should try to use lux more times, but I lack the needed
free time. However the quality of the visualization really could help to
spot misalignments, and so this effectively help to place better/missing
CPs and have a better panorama as a result.

  So, thanks to Kay for this tool!

  sincerely,

  Luís Henrique

Re: [hugin-ptx] Re: Hugin places first (left) image in the middle of the panorama - Why?

[Luís Henrique Camargo Quiroz]

   Hi Len!

   In your first message you told that you never saw in the GUI things you
read in FAQs. So I guess you do your stitchings, all this time, using the
default option, the "simple interface". I use the "Specialist", but the
"Advanced" can help you too with our needs, so, please, look for that in
the fourth  menu.
   Now, when you load your photos, you can see in the first tab (photos),
when display/general (right column, after the photos' information display)
is selected, an "anchor" column. Now, right clicking, you can select the
photo you want for the center position. You may have already read about two
kinds of anchors: position and exposition. But there are other ways to
position the image with, say, absolute precision! As the anchor will not
move to the sides, albeit is can be rotated and even have some pitch
(inclination), so you can define a precise yaw angle to fix this image
center (and as result the whole panorama) to a know position, 0 degree
being the center of the canvas/panorama. If you right click you anchor, or
double click it, you can *enter* the values yourself. Just think that,
after an optimization to align the photos, some values could change, but *not
the yaw*.
   And besides dragging the panorama with the mouse, in the fast preview
window (with the GL in the icon) you can find a move/drag tab, with some
fields available to enter angular values to apply to the shown preview. The
"regular" preview window, which is slower but with a higher image quality,
also has a "numerical transform" for the same purpose.

   It may be a matter of personal taste, but I like to start my photos
pointing to the north, so the center of my panoramas is the true north. Of
course, for your planetary software, the center appears to be the East. Or
South? If the pano is a 360 one, the borders will be +180 and -180, not 90
deg.

   Well, I missed you used some of the preview windows already, so maybe
you have discovered the numerical transformations yourself.

   Be a happy Hugin user!

   sincerely,

   Luis Henrique

Re: [hugin-ptx] Is there any way to keep pixels unchangeable with Hugin?

[Luís Henrique Camargo Quiroz]

   Well, by Tomas' message I understand  that if you "cancel" vignetting
the input will be unmodified in the output.
   In nona.txt I read:
# Vm   vignetting correction mode (default 5):
#  0: no vignetting correction
#  1: radial vignetting correction (see Va, Vb, Vc, Vd
options)
#  2: flatfield vignetting correction (see Vf option)
#  4: proportional correction: i_new = i / corr.
#
#  default is additive correction: i_new = i + corr
  so you have to put a Vm0 in a Hugin project file.

   Indeed, in your email from the last 28th you tell us that the pto file
has lines like:
*i w640 h512 f0 v17 Ra0 Rb0 Rc0 Rd0 Re0 Eev0 Er0 Eb0 r0 p-0.82153530183907
y-33.6586917800566 TrX0 TrY0 TrZ0 Tpy0 Tpp0 j0 a0 b0 c0 d0 e0 g0 t0 Va1 Vb0
Vc0 Vd0 Vx0 Vy0  Vm5 n"000_encoded.png"*

   So change Vm5 to Vm0 and let's see if now the results are what you
expect to be.

   regards

Re: [hugin-ptx] Something simple I'm doing wrong with 360 pano: sideways/upside images?

[Luís Henrique Camargo Quiroz]

   Hi,

   This seems very strange to me. If the images which remained in a
horizontal position also have sensible CPs, as the turned sideways have,
then at least there must be some big errors, or else the initial and final
image from your circle are missing CPs in between. Please check this, and
maybe try some manual CPs yourself (more CPs) to force the circle to close.
Could you share just the project file?
Have you closely examined when the sequence turns from horizontal to
vertical? There must be wrong CPs there, or a very close group of CPs ;
spread them, trying to make the images harder to rotate.

Well, don't forget to reset positions before you try again. Also, check
if the EXIF data and lens parameters are good.

Let's see what happens,

regards,

   Luís Henrique

Re: [hugin-ptx] Re: Errors building latest hugin default source

[Luís Henrique Camargo Quiroz]

   Hi Abrimaal,

   Just to tell that I use a color calibrated monitor, and also have
calibrated a few other monitors (none of them CTRs), and I know by
experience that color management *and* color profiles do make a big
difference!
   Some pointers: hardware like the Datacolor Spyder5EXPRESS
,
and software as DisplayCAL  and ArgyllCMS
. Even my former (satellite) TV provider
offered, as a paid service, the color calibration of digital TV sets.

   And now I have found some links which I will see myself in order to
better understand all this :)

Re: [hugin-ptx] Hugin freezing during blending

[Luís Henrique Camargo Quiroz]

   @Bruno: I think you have  used ptodummy to generate (missing) files for
the pto, right?
I tried this recently, however it is not working here, Debian testing,
with this error message:
convert-im6.q16: unable to read image data `/tmp/9Y8FDe8hK7.pnm' @
error/pnm.c/ReadPNMImage/1340.
convert-im6.q16: no images defined `im31.jpg' @

  Any clues about this? Thank you!

Re: [hugin-ptx] Correction of heavy noise?

[Luís Henrique Camargo Quiroz]

   Hi Mathias (if I recall well)


   I had problems like you long ago, with lots of messages about problems
along the processing of the panorama. It turned out that using
"--blend-colorspace=IDENTITY" for enblend and enfuse solved the issue. Have
you already used this parameter?

Re: [hugin-ptx] Feature requests for Multiblend 2.0?

[Luís Henrique Camargo Quiroz]

I have made some panoramas with circa 2.7 GB in a tif equirectangular
file.  However I had to grew my linux swap partition more than one time
until I managed to finish those panoramas, and my swap has 72 GB currently
(and only 16 GB physical memory).


  regards,

   Luís Henrique

Re: [hugin-ptx] pv - a multiplatform FOSS panorama and image viewer

[Luís Henrique Camargo Quiroz]

   Hi Kay!

   I just cloned pv and installed the dependencies, but had a problem.  I
am using Debian (testing/unstable, i. e. bullseye/sid), and  vc-dev here is
version 1.3.3-4, so I had to remove it and install vc 1.4 from git.  Now I
succeeded!

   It is time to see the options, but it is fast and will be extremely
useful,

  many thanks!

  Luís Henrique

Re: [hugin-ptx] pv - a multiplatform FOSS panorama and image viewer

[Luís Henrique Camargo Quiroz]

   Hi Kay,

   I have interest in pv, but have not had success compiling it in the
past, with gcc.  Then, as I am busy with an ongoing PhD (and I even was
abandoned -- yes, months of emails, messages, even some phone calls! -- and
had to ask the intervention of other faculty members) and have lots of
things to do, even with an extra additional year, I have not tried any
more. But I will do, I will, in a few weeks, try to compile pv again,
because I think it will easy a lot the final editing of my panoramas, which
I still try to do as my hobby (I think I deserve)

   But, just now, I am cloning my notebook's HD, because it is old and
started to emit bad alerts.

   I put an 'event' in my calendar and will try to compile pv in a month or
even sooner, and I will report back.

   go on,

   regards,

  Luís Henrique

Re: [hugin-ptx] Re: Auto calculation of Yaw, pitch and roll failed in some computers

[Luís Henrique Camargo Quiroz]

   Maybe discrepancies in lensfun? Not all the same version, not all
updated?

  Run lensfun-update-data.  Hugin only can benefit from good lens
parameters if they can be found in the database.

Re: [hugin-ptx] Re: Fails on Catalina

[Luís Henrique Camargo Quiroz]

  Hi Bill,

  I don't use Apple, but the error is very clear, as you can see in the
picture: there are spaces in the project name, and it was not Hug, but
"1BM_4873 - 1BM_4880.pto". This is the "default" name, which you can at
least make without spaces, going to preferences/fine names.
  Are you sure you named your project as Hug.pto?
  And about "For sure will no longer consider buying the professional paid
version, [...]" you are wrong, Hugin is 100% free, there is no paid version
anywhere! Or else someone is deceiving you.

  If you try once more, good luck, and you can be sure many in this list
you help you gladly and for free. And some are very clever and
knowledgeable about Hugin and panoramic photography!

   regards,

   Luis Henrique

Re: [hugin-ptx] Hugin is driving me crazy

[Luís Henrique Camargo Quiroz]

  Hi,

  I think that automatic control point detection is to blame here. Have you
checked if the control points are right?
  What are the CP errors values?

Re: [hugin-ptx] viewing PTO files without stitching

   Great Kay! I will try to compile it this time, the features of your pv
are really compelling and would easy a lot to build great panoramas!

  Hi Rogier?

  Phone photos... I recall they sometimes have EXIF data not correctly read
by programs. Haw are your exif libraries, and are your lensfun updated
also? Maybe this helps,

  And let stay at home more... hopefully have more than 20 panoramas to
generate ;)

Re: [hugin-ptx] Confusion regarding changing CP distances

[Luís Henrique Camargo Quiroz]

   Hi Jud,

   Did you changed the pano size after optimizations?  By default Hugin
chooses a pano of 3000x1500 pels, for a complete equirectangular, and shows
the errors relative to this size.

   I also did not understand why my errors "suddenly" increased a lot, but
I noticed that I had chosen the final max size for my photos and this
changes how the errors are numerically presented.

   This seens your situation: mean ~0.5 for a max 1 or 2 (for 3000x1500,
probably) and then (mean) 10 and max 40, perhaps your canvas increased to
about 12000x6000?

Re: [hugin-ptx] Problem building Enblend

[Luís Henrique Camargo Quiroz]

   Hello,

   My exiv2 in Debian testing is 0.25-4.
   I compiled enblend-4.3.0-1529hg-Linu. It was on Oct. the 27th.

   The biggest problem I have met was while hg cloning hugin, it took
several tries until it succeeded. And it was slow.

Re: [hugin-ptx] Re: Photometric alignment changes the reported control point distances

[Luís Henrique Camargo Quiroz]

   Hi,

  I think one important thing to observe is the size of the output. By
default Hugin starts with a 3000x1500 equirectangular, and I place CPs and
do many optimizations with this output size. Lter, when I start to generate
bigger "previews", or the biggest, final result, the errors apparently
increase, which is (should be, I never checked) proportional to the size
increase.  Is this effect the culprit in this case?

Re: [hugin-ptx] Radiometric aberration

[Luís Henrique Camargo Quiroz]

   Hi Luis,

   I faced similar problems, but with (mainly) red dots instead of magenta,
and a slow stitching while stacking exposures. I had problems with the
color spaces I was using in Hugin, in my camera and in the development of
the raw files. Try this option, both in enfuse and enblend; I hope this
solves your problems:
 --blend-colorspace=IDENTITY

Re: [hugin-ptx] Hugin isn't starts!

[Luís Henrique Camargo Quiroz]

  Hi, only the xml, the "dump" file is not human readable.  Please, if the
xml were big, better to upload to a file share service (dropbox, google,
etc) than to send by email.

  *Also, have you tried to delete the "preferences" and restart hugin?*
Please see how in  the last paragraphs here:
https://wiki.panotools.org/Hugin_Preferences, Troubleshooting,

  And, yes, Hugin is not a commercial product, with paid support. You can
find here in this mail list lots of ideas, problems, solutions for the
problems, etc, many times from real experts (far better than paid support!)
with Hugin and panoramic photography. See the tutorials in Hugin and
Panotools sites.

  Hi Yuri,

  The important thing to know will appear in the files listed in the window
about the error that you attached to your email, if you choose OK.
  Besides that, you could also delete the hugin preferences file, which
will no be destroyed with a reinstallation of the program. I don' t
remember the name of this file in Windows... google for it.  You can also
try to start Hugin with the CRTL key pressed, this could help,

Re: [hugin-ptx] missing tile after photometric correction

[Luís Henrique Camargo Quiroz]

   Hi Andrei,

   I suspect there is a great amount of image superposition (overlap) there
where the tile is missing, is that the case?
   When I dealt with those problems in the past I used masks to reduce the
overlap between images, that helped. Others advice to change the order of
the images, this can help too.

   BUT perhaps a better way is to use enblend with the parameter
--primary-seam-generator=nearest-feature-transform and you could also try
--pre-assemble.

   Did this help?

Re: [hugin-ptx] RAW support with hugin ?

[Luís Henrique Camargo Quiroz]

  Hi Albert,

  One point to consider, besides the existence of dedicated programs for
dealing with RAW files, is: how shold Hugin "develop" the photos? Should it
convert in a basic manner, without manipulating exposition, color balance,
noise, for instance?
  It is better to leave all the possibilities of RAW file development to
the specific programs for this purpose, so Hugin could concentrate on its
goal: join different photos in order to compose a very good panorama!

  Don't you agree?

  regards,

  Luís Henrique

Re: [hugin-ptx] Stitching in Mosaic Mode

   Hello Kai,

   Have you seen this tutorial already, "Stitching flat scanned images

   Your pictures are of a flat image (the painting). I think the settings
you will find in Hugin are for regular panoramas only, where the camera
should only rotate or have limited, small  translations.

   Good luck,

Re: [hugin-ptx] Images rotated on Hugin Control Points tab

[Luís Henrique Camargo Quiroz]

  May I add an intermediate case?

  Some times, trying to add (manually) control points in branches of trees
in photos taken near and/or at the vertical, with different yaw each photo,
it is harder to see matching features because of the orientation of the
photos -- or tree branches -- not the same, say, the first (left) image as
base and the right one turned laef or right or even upside down... Sure it
is a great exercise (or pain) for my neck!
  In those cases it would be extremelly useful if I had a control to just
turn one or *even both* of the images a specified amount of rotation, just
for the display, not for the physical orientation of the picture. This
feature would be turned on when desired -- not default, nor simple mode
interface --, and increments by 1 or by 5 degrees should suffice.

Re: [hugin-ptx] Re: hugin on El Capitan and older versions

[Luís Henrique Camargo Quiroz]

   I would also add the fact that simply adding control points, whether
manually whether automatically, is not enough for stitching: it is required
a geometric optimization in order to position each photo where due.
   Also, check what is the user interface you are using. If it is "expert"
or "advanced" you *have* to optimize; if it is "simple" (perhaps
"automatic", the first option in the list) but you had to add control
points yourself, the automatic optimization that would happen will not
start, *you* will start it - after creating enough control points.

   So, see the help as Carl told you, the tutorials at
http://hugin.sourceforge.net/tutorials/index.shtml, and you will know what
is happening and how to use Hugin successfully in all situations.

   So... good panoramas!

   regards,

Re: [hugin-ptx] What confuses Hugin

[Luís Henrique Camargo Quiroz]

  Hi Steve,

  Have you *optimized*, after finding the control points, for yaw, pitch,
roll, and perhaps (better after yaw, pitch, roll, in a second step) also
for positions? It is this optimization that reduces the initial errors and
thus correctly repositions each image in order to build a panorama.
  In this process Hugin itself will correct for perspective in your photos,
so the images will perfectly match if you have little parallax.

  If you did optimized, I did not understand well what could have happened,
so some screenshot of your result, if possible, would clarify for us your
problem.

  Hugin is a great software and you surely should get stunning results with
it.

Re: [hugin-ptx] Re: Hugin-2016.0.0. cmake fails

[Luís Henrique Camargo Quiroz]

  This card, a GeForce 9600M GS (seen from your lspci command) is really
old.  I think this -- age --  could be the culprit.
  See https://en.wikipedia.org/wiki/GeForce_9_series or
http://www.videocardbenchmark.net/gpu.php?gpu=GeForce+9600M+GS

[hugin-ptx] video for Hugin

[Luís Henrique Camargo Quiroz]

Hi,

I just saw the video Sourceforge is planning to put in the Hugin
summary.
The idea of having a video is good, but the video at <
https://youtu.be/EYa21pinHJo> should have been prepared in order to
show a *real
use case. None* of the situations shown in the video are of a real panorama
editing/stitching (altough the "panorama" with the animals could have its
purpose), so, they are absolutely misleading.
Some of the tutorials, as
Stitching two photos together


or
Stitching Multi-row photos together


could be used in order to create a new video which really shows what Hugin
is intended for, and how to use it correctly.

   In few words: please don´t put the video at 
in Hugin project summary!

   Luis Henrique

Re: [hugin-ptx] Save Enfuse output to predefined path

[Luís Henrique Camargo Quiroz]

   Hi,

   I think you could not use a wildcard in the output file name, so you
should use
   -output=c:\pictures\fuse\result.tif
instead of
   -output=c:\pictures\fuse\results*.tif

   regards,

  Luís Henrique



2015-07-02 12:28 GMT-03:00 Digicrea pentaxianbelg...@gmail.com:

 Hello,
 I have following problem,
 I want to save the image output from enfuse at a certain path.
 Its no problem to tell Enfuse where to find the input images, but pointing
 the output to somewhere fails.
 The help file tells me to use -o or --output, but that didnt work in any
 way.
 I tried ( simple example )
 enfuse c:\pictures\fuse*.tif enfuse_additional_parameters= --wExposure=1
 --wSaturation=0.1 --wContrast=1 --levels=auto
 --output=c:\pictures\fuse\results*.tif
 So, in this example, i want to save the output in
 c:\pictures\fuse\results\ Can anyone tell me what to use to direct the
 output ?
 Many thanks !
 Regards
 Marc

Re: [hugin-ptx] Feature request/Bug fix

[Luís Henrique Camargo Quiroz]

+ 1 vote for this proposal

2015-05-28 9:57 GMT-03:00 paul womack pwom...@papermule.co.uk:

 When working on a stubborn optimising problem, it is helpful
 to work stepwise.

 To faciliate this, Hugin's optimiser tab had an option:
 Only use control points between image selected in preview window.

 This works well; however, assuming that an optimisation
 gives a good average and standard deviation, but has a high max,
 it is obvious that some duff control points exist.

 Now, the easiest way to get rid of these is the
 Control Points dialog (F3), which can list control points
 in distance order, making deletion quick and easy.

 But this shows ALL the control points.  In a partially
 completed optimisation, the un-optimised images
 (UN-selected in the preview) will have very large errors,
 and this make removing the large(st) errors
 for the selected images very difficult.

 Proposal/Solution:

 F3 should only show CPs for image selected in preview window,
 possibly also under the control of the option in the Optimise tab.

Re: [hugin-ptx] autopano.exe return errors when run with huggin.

[Luís Henrique Camargo Quiroz]

Hi Brandon,

You told your friend has two Hugin versions... so, who knows, perhaps there
is some mess if the PATH variable calls the binaries from the wrong
version instead of from the actual, desired directory? I don't recall if
windows prefers the binary from the current directory or from the PATH.
Just an idea.

Good luck!

Luís Henrique

 I haven't used autopano as a CP tool for ages, and don't run Windows,
 so, sorry, have no other ideas.

 I did consider the antivirus. Both computers have the same antivirus
 program with the default settings, in this case avast. In my experience
 when avast has a problem with a file that I want to run it will pop a
 warning telling me so. When I tried it on the laptop there were no
 antivirus warnings.

 That said the next time I get a shot at that computer I will run autopano
 from the command line and double check it works as expected.

 What do you use for a CP finder?

Re: [hugin-ptx] Error: Directory Canon with 7936 entries considered invalid; not read.

[Luís Henrique Camargo Quiroz]

Hi,
 
Could it be a problem because lack of space, or directory capacity
(number of files) exceeded?
7936 seems a lot of files (or entries).  What are the contents of
this directory, only the photos to stitch and the hugin generated files?
I understood that you generated control points, etc (perhaps masks,
saved the project, ) and the problem arises after you press
stitch. Immediately, or afer some time? Is some log generated?

Let´s see what this problem is!

Re: [hugin-ptx] Differences between preview and result image

[Luís Henrique Camargo Quiroz]

Hi Samuel,

Certainly this girls appears in one of your photos, but, just where
her head is, there´s another photo, in a upper row, with the building
behind, and not the girl. Hugin used both photographs to blend the
result, and choose - automatically - parts of one and of the other photo. 
Also, when she appears, you can see that her legs are not complete,
there´s a a very narrow 'ground' below, and in the blended panorama this
made her legs lika a phatom.

You can/should use masks, or to try to vanish with the girl (exclude
mask) or to preserve her (include mask).  Try, you will understand what
to do.

   Happy panoraming,

   Luís Henrique

Re: [hugin-ptx] Feature idea: brightness adjustment in control points tab

[Luís Henrique Camargo Quiroz]

Nice idea! Especially the automatic contrast in the zoom area!

Luís Henrique


2013/3/27 Brent townsh...@gmail.com

 Very often, especially with 16-bit images, the area of images where I
 would like to add or inspect control points is too dark or too light to see
 any detail.   Although the preview windows can adjust the EV of the
 display, the control point windows are fixed.  The result is a lot of
 squinting, dimming room lights, etc, to be able to see where the control
 points are or should be.

 It would be great if this could be handled by one of a few possible ways:
 - photometric mapping in control point windows same as in previews
 - separate brightness/contrast control in control point window
 - automatic contrast-maximization in whatever zoom area the control-point
 window is in

 To expand on the last point, I'm thinking that histogram-normalization of
 the pixel values over the two image regions being displayed would stretch
 the dynamic region to match -- similar to how the small zoom region under
 the cursor works now.

Re: [hugin-ptx] Lens calibration trouble: cannot optimize

[Luís Henrique Camargo Quiroz]

Hi Pt,

I'm not yet acquainted with the new interface, but you should try the
'advanced' or the 'expert' modes. Problably you started in the 'basic' and
simpler mode, where many features are hidden.

Yes, I can confirm: here, using the 'advanced interface', in the photos
tab, at the bottom, I see the optimizer options, for geometry and for
photometry.

I have to do some more tests and ask/report here, but in my last project,
using linux and a self compiled hugin, the photometric optimization crashed
the program in my 2 or 3 tries...

bye,

Luís Henrique


2013/3/13 Peter Suetterlin p.suetter...@royac.iac.es


   Hello list,

 I recently bought a new lens that I'd like to calibrate for lensfun/hugin.
 I thought that might be a nice point to also try the latest hugin from the
 repository.  However, now I'm stuck with the new GUI.

 As suggested in the tutorial, I took an image of a building with nice
 straight
 features and marked (even) three lines across the image - but there's no
 way
 to optimize.  There are no tabs, and the menu entries for optimize (and
 exposure) in the 'View' menue are greyed out.

 So what now?  Revert to my old 2011 version?  That cannot be the
 solution

Re: [hugin-ptx] Re: no output photo created

[Luís Henrique Camargo Quiroz]

   Hi Don,

   Yes, this seens to be the problem. Your Hugin installation is fresh, but
the hugin project is still the old one...
   Most problably the previous installation would work with a new (or
modified project) with file names/path names with problematic characters.
To avoid starting your stitch project again, ou can try to edit the .pto
file and change the path names to the new names.

   Now I also avoid using accented letters, etc in my paths and project
names. If this does not cause major problems when I use the linux Hugin,
this still truncates (from the special character on) the progress messages
that appear for each photo when running the Hugin Batch Processor.

   By now you should have had success with Hugin... if not yet, you surely
will!  Best luck!

  regards,

  Luís Henrique

 I think the problem may be that although I have uninstalled and performed
 a clean install of Hugin since creating the new account (DonandSue), and I
 am working under the new account, Hugin is still using the old account name
 in the path when it is doing the stitch.

Hi,

 Well sorry as non-english speaker it's pretty hard to make it clear.

 i have many Tiff files with temperature information and I know that
 they overlap since they are extracted from a thermal movie carried on
 a plane. So my aim is just to past the images together without any
 change to the value since they will be the base to some really
 accurate analysis.
 It seems that nona as well change the value however  I will try the -l
 1 option in enblend and see if it works.
I don´t remember if you already told how you got your images. I
mean: are your individual pictures a copy of the movie frames? Do you
know some parameters of the lens used to make the movie?
As Hugin uses the lens geometry (image distortions, etc) I seems
sensible that nona could change yor values, as nona generates images
projected on a sphere (for panoramas) or over a plane, for mosaics --
which I guess is your problem: a planar surface with a field of
temperatures.  [post note: I just checked your first message and you
told us about /a temperature raster mosaic/]. Have you seen
http://hugin.sourceforge.net/tutorials/scans/en.shtml already?

Did you create the control points by hand, or with cpfind or other
automated methods? Your hot surface has enough distinctive features to
select as controls points?
I apologize if those questions are already answered in previous
messages... I can´t remember it all ;)


 The problem of Grass is that I need coordinates for that, my final
 image will be georeferenced afterwards but for the moment they don't
 have any geographical information so i can't use any GIS tools

 Thanks again and if you have a magic option for nona to avoid the
 change of the value i would finish this crazy project!

Luís Henrique

 (i haven't found the core)

 The video card is a radeon 9200 and the os is 32 bit, but the same
 happens on another pc with ubuntu 12.04 64 bit with a nv17 card
 and nouveau drivers.

 Thank you in advance.


Hi,
Have you checked if the video driver is updated - in the installed
ubuntu, perhaps possible to update with the live version too?
Once I had such kind of problems with my debian. The fresh compiled
Hugin versions keep crashing when I tried to show the fast preview
window, and weeks later I noticed my Nvidia proprietary driver was
already a bit old. I don´t know if the fast preview window works well
with the nouveau driver, so one test you can do is with the proprietary
Nvidia one, if your machine has such video card, of course.

Good luck!

Luís Henrique

Re: [hugin-ptx] 360 degree panorama *very* distorted

[Luís Henrique Camargo Quiroz]

  Hi Marcus!

  Have you checked if the first and last images have control points
linking them togheter?
  Once I had the same problem of not getting 360 deg field of view, in a
row of pictures, using automatic control points. But I can´t recall my pano
being so distorted as yours. Many times I do my first optimization of yaw
and pitch only, leaving roll=0, perhaps this could help you; further
optimizations can/should consider roll, of course, but your values seen
fine  HAHA! please, turn off the translations X, Y and Z, they should
be used only for flat images, aka mosaics.

   Good luck!

 Hi,

 This is probably something simple, but I really can't figure out what I'm
 doing wrong.
 In hugin I have 15 images connected using 421 control points (mean error
 0.2px, max 2.4).
 After the optimization the images range from yaw=-133.7 to yaw=173.4.
 That's ~307 degrees, but why not 360?
 307 degrees is close, but now when I press Calculate Field of View on
 the Stitcher tab it gives 180x76 which is nowhere close to 360 degrees
 horizontally.
 The final image becomes extremely distorted. After changing the field of
 view to 360x80 the stiching produces this:


 https://lh3.googleusercontent.com/-kANvDRS4djc/UDFuiSY4NAI/ACY/ZHbUS-XaFcc/s1600/DienteDeInca_blended_fused.png
 This is supposed to be a landscape, but is so distorted you can't even see
 that.

 The image list looks like this:


 https://lh5.googleusercontent.com/-jPTWT3bvgHk/UDFuqXKOfUI/ACg/TYIq-RCOD9E/s1600/image-list.png
 Any ideas?

 At least some weeks. We are now in the middle of the holiday season

Re: [hugin-ptx] Prioritize images?

 I'm trying to stitch a panorama where I have one image which is, for

 else. Fortunately, I have good overlap, so the damage isn't very
 large. If I exclude the image entirely, only a small part of the final
 panorama is missing, and I think I could live with only that small
 part being blurred (or maybe I could fix it afterwards). However, if I
 include the image, it makes for quite a large part of the final
 panorama. Is there a way to prioritize images, so that a given part
 of this particular image would /only/ be used if there is no other
 image covering that exact part of the panorama?

 I'm on 2011.5.0.dfd9dc55c39a (GUI overhaul, from the nightly Ubuntu ppa)

Hi Thomas,
What about using masks? You could exclude almost all the blurred
photo, and keep only the 'missing' region - the one not overlapping with
other images.

Re: [hugin-ptx] Just upgraded to Linux Hugin v2011.4.0.cf9be9344356

[Luís Henrique Camargo Quiroz]

Hi Gnome,

Have you checked if your video driver is updated?

When I updated my nvidia driver a few weeks ago I could finally run
Hugin (fresh compiled from trunk) again -- until then I thought the
problem was with wxwidgets or something else.
In the same machine however, whit windows (and older Hugins) I was
still able to run without problems! And the windows driver was almost so
old as my linux one! Many months old!

Good luck,

Luís Henrique

 Created a new project in the new version, clicked OpenGL Preview - and
 Hugin silently died again.

 Wiped out the .hugin file again and was able to make the workaround work.

 Sigh. Programming OpenGL sounds like a major headache!

Hi again!

 Hi!

 Don't know if you're using Linux, too, but doing a dist-upgrade on
 Linux updates everything if there's an update for it in the
 repository. I don't know if the driver was updated or not, the laptop
 uses an Intel 855GM chipset (ancient!) and may well not have been
 updated for a long while. But Hugin didn't have any problems with
 OpenGL preview on it until 2-3 Hugin updates from Sid ago. Those
 updates were just updates of Hugin from the Debian Sid repository.

Yes, its Debian, but Squeeze. I got updated drivers from nvidia
site, because in Squeeze repositories it is old...
Perhaps this ancient graphics chip lacks some functionalities Hugin
now requires?

 Same version of Hugin works with no problems on my 64-bit AMD Phenom 2
 system, with the same version of Linux installed on it. Only
 difference is the desktop uses NVidia video.

 I still suspect it's a bug in Hugin's coding somewhere, like a missing
 try/catch or something. I suspect that's why Hugin just dies - no
 error message, no log, just gone. Also, I'd expect other
 photoprocessing software I use that also uses OpenGL would have
 similar problems.
In my case only the splash screen appeared, very shortly, and then
boom, no error messages, nothing, Hugin simply died.

 Anyway, I keep upgrading and hope. It would be nice if there was an
 option in the huginrc file to disable or even remove the
 overview/panosphere, I think one of the Hugin developers seemed to
 think that was connected with trying to use OpenGL before it was
 initialized, or something like.

Yes, such an option (huginrr, or a .ini file in windows) would be
really valuable! The other thing I can say, but it´s not really Hugin
related, is that I´m very tempted to try Debian Sid very soon.

Luís Henrique

 For some unknown reason, after correcting a number of issues, the
 Quicktime VR movie I created becomes like an inverted cone view (imagine
 standing at the bottom of an inverted cone looking up):


 http://www.powersystemadvisors.com/cheungs/Panorama/DSC_0100-DSC_0177Final_fused800.mov

 as oppose to the far more pleasant street view:


 http://www.powersystemadvisors.com/cheungs/Panorama/DSC_0100-DSC_0114-1.mov

 I have no clue what I did to cause this. The jpg was created by using
 Hugin, and the Quicktime conversion was created using Pano2QTVR.  The jpeg
 appears to be normal:


 http://www.powersystemadvisors.com/cheungs/Panorama/DSC_0100-DSC_0177Final_fused.jpg

 So, I am assuming I selected something when stitching that caused this.
  Anybody?

  Hugin has lots of photography jargon, but this is inevitable, there

 If a label, e.g. next to a checkbox, is needed, what about cutting
 down the acronym and let it say user interface mode or maybe just
 interface mode? Or even user mode?

 Is the word interface easily understandable in English by someone who
 doesn't have any technical knowledge about computer programs?

 I don't know this since English is not my first language, but in the
 Danish translation, GUI would probably just remain GUI (which would be
 confusing) since we, to my knowledge, don't have an acronym for that.
 So I also vote to avoid the word GUI.

I agree too: interface is better than GUI -- especially for beginners :)

I hope I could compile and test the overhauled GUI Hugin this weekend.

[hugin-ptx] questions arisen while translating

[Luís Henrique Camargo Quiroz]

Hi,
I just started some translations, for brazilian Portuguese, and this
forced me to (1) verify some things in the program and (2) try to figure
out the best version/translation for some sentences.

Now I´ve found the following, about a infobar, but I can´t find any
checkbox in preferences, or elsewhere, where to hide/show the infobar.
I´m using the 2010.4.0_rc1 for Win32.


You have hidden the infobar, which shows hints about selection of
projection.\n
If you want to see the bar again, activate the bar in the preferences again.


Where should I ask for help, in case I were not sure about the real
meaning or intention of a sentence to be translated?

thanks,

Luís Henrique

 There is a bar that appears on the fast preview sometimes to give hints
 when the projection and field of view might not be ideal. It can only
 appear when Hugin is built with wxWidgets 2.9. With wxWidgets 2.8 (the
 current stable version) the hints appear on the status bar instead.
...
etc etc...

Thank you, James!
So the windows version was built against wxWidgets 2.8.
I have thought the infobar appeared in the Assistant tab.
Perhaps tomorrow I could finish this (first) translation. Later,
I´ll try to ask for some clues for a better, more meaningful translation.

Re: [hugin-ptx] File Naming Convention (New Hugin Preference)

[Luís Henrique Camargo Quiroz]

 Hi all,
Hi!
 by default when saving a project file, Hugin suggest a name based on the 
 names 
 of the input pictures.

 picture names out of the camera are by default just sequential number and not 
 very meaningful.

 I store all individual images related to a panorama in a single folder with a 
 meaningful name - e.g. if this was a panorama of the New York skyline I'd 
 call 
 the folder something like NYskyline; and the project NYskyline.pto and the 
 resulting panorama NYskyline.tiff.
Me too.
 This is very personal.  Others are likely to do different things.  Some users 
 may prefer the existing naming convention, some users may like a different 
 naming convention all together.  It's a *preference*.

 For a while I maintained a local patch to automatically take the folder name 
 as base for the project file suggestion.  Now I wrapped it in a preference 
 (disabled by default), so it is available to everybody without changing the 
 world of those who prefer how Hugin has done this so far.
Nice idea, thanks!
 The next logical step is to fix the names of the intermediate files, e.g. the 
 remapped images.  Currently it is the project file with appended sequence 
 number starting with .  Again, that sequence number is not meaningful.  
 I'll want to replace it with part of the image file, then it will have a 
 meaning: a reference to the original image that was remapped.  Will make that 
 part of the preference so that it won't change the expected behavior to those 
 who prefer how Hugin has done this so far.

[hugin-ptx] Re: Lens calibration gsoc project -- photos needed

 HI All

 Tim Nugent's summer of code project, to develop a program for
 calibrating lenses by the straight line method, has almost reached the
 point where lots of test data are needed.  So as his mentor, I am
 issuing a call for pictures to test it with.
 ...

 We promise not to publish your photos or use them for any nefarious
 purpose, but be aware that neither email nor that ftp site is
 particularly secure against evildoers.  So don't send us your
 masterpieces -- they probably wouldn't be any good for lens
 calibration anyhow :-).

 Thanks in advance, Tom

   



Hi Tom!
Would shots taken with a handheld or with conventional tripod camera
be useful?

best regards,
Luís Henrique

[hugin-ptx] some GUI ideas: multilayer tiff?

[Luís Henrique Camargo Quiroz]

Hi,
I forgot to ask, some days ago, when the ideas about the GUI are
circulating: older Hugins have the option to create a multilayer TIFF
while stitching, and newer versions don´t. I think it was a useful option.
Also, the stitch.txt file in the hugin\doc folder does not mention a
TIFF_multilayer output format anymore, as the older nona.txt did. the
last time I created a multilayer tiff - months ago - I had to manually
edit the pto file to change this missing option.

thanks,

Luís Henrique

[hugin-ptx] Re: Clouds in hi resolution pano (Celeste 2.0?)

[Luís Henrique Camargo Quiroz]

Yuv escreveu:
 hi all,
   
Hi! See point 2 below, please.
 I'm currently dealing with a lot of clouds (when traveling quickly
 through many locations I have no other choice than take the meteo
 conditions as they are). Since the introduction of Celeste (that works
 great, thanks Tim!) this is no longer an issue for the proper
 alignment and stitching of everything but the clouds. However in multi-
 rows high resolution shots the clouds end up being an issue at the
 blending stage. The rows become visible.

 The lazy way to deal with this is to mask out the sky and replace it
 with whatever photo editor is at hand, but the result inevitably looks
 artificial (shade zones on the mountains and so).

 When Tim was coding Celeste, we sparred about what kind of mask should
 Celeste generate around the clouds, if any.

 Now, having such a mask could be useful for the following idea,
 assuming the clouds movement is constant throughout the photoshooting:
 1. generate control points for the static parts in the image. Use them
 to position the images in relationship to one another and create the
 master panoramas, using Celeste to prune CPs from the clouds and mask
 the coulded areas.
 2. generate control points in the clouds (area masked by Celeste) and
 calculate the translation related to the positioning in 1 (which is
 the translation vector multiplied by the time differential between the
 reference image and the current image)
   

Ok, but, if I don´t misunderstood: in the perhaps usual case of wind
in mainly the same direction and speed, if someone take shots for a 360
deg panorama, the algorithm has to deal with many cases: clouds
approaching the camera, then (say, rotating camera clockwise) coming
from left, then going farther, then coming from right, and at 360=0
again towards the photographer. I think that any solution to this
problem - cloud movement at 360 degrees apnos -  would distort the
sky  somewhere in the result.
But, in other cases, when clouds are always going in the same
direction/speed, this solution is great!
 3. use the translated cloud images to generate an additional panorama
 of the sky
 4. mask the sky out from the static panorama and add the sky panorama
 as a layer

 there will be some areas of the sky that will be empty (e.g. when a
 cloud moves behind an object or out from it), but those will be much
 smaller areas to deal with in an image editor than generating the sky
 artificially or dealing with the shift across all images.

 to do this we need:
 - an additional category of CPs to compose the sky panorama (sky-CPs)
 - a measurement of the displacement of those CPs related to the
 position of the image in the static pano
 - some math to average / optimize the displacement measures
 - some glue/script to generate the second panorama
 - a tool to mask the sky from the rest of the panorama (I don't think
 that Celeste's mask are fine enough for that).
 - some glue/script to add the mask and the sky to the resulting
 panorama.

 does this sound logic? or have I missed something? should I record
 this as a feature request? maybe a future GSoC project?
