Re: [hugin-ptx] idea for CP deletion

Bruno,

If i'm not mistaken, the -p in cpclean only optimizes each pair of images 
according to the standard deviation you specify - if you are still at risk 
of removing all CP's between images, right?

I haven't committed the code, since it requires more changes than just
the projection functions. Expect that soon.

There will be a new projection, called the Thoby projection, with two
optional parameters (the two coefficients that default to the Nikkor).
The Nkkor is not truly orthographic, but that projection will remain
untouched, for compatibility purposes.

I also think this is a very good idea.

FWIW, in terms of Hugin UI/UX, I think it is mostly already good enough. 
But, and it is a big but, there are a bunch of little annoying things that 
make the process sort of non-intuitive. Where is the best place for me to 
report such stuff?

 everything else secondary - to the extent that only the preview is visible
 during a normal workflow.
 
 This approach is now practical since we got background loading of photos,
 the question is, do we want it?

I think this is very good idea. It makes the application more widely
usable for a wider audience, while at the same time allowing deeper

so I'm all for it. But does it fit in yours?

2011-01-04 Thread Jeffrey Martin
We are reaching a point in the discussion where it is appropriate to compare 
ptgui and autopano pro.

ptgui has the hugin-type UI while Autopano Pro has the preview 
window-type UI.

APP is geared better towards people who don't want to understand the 
technical aspects of stitching. the UI is excellent. 

Likewise, PTGui is geared towards people who want to understand the 
technical aspects of stitching.

Also, both programs do a very good job of doing a fully automatic stitch. 
It's when that doesn't work, that the usage of the programs is very 
different.

It would be interesting to offer both types of UI, in my opinion. We already 
have the technical one, and it only needs small fixes before I'd call it 
very good.

Re: [hugin-ptx] ptmender or nona?

2011-01-04 Thread dmg
They both use the same transformation code (libpano).

PTmender is simply a transformation program. It does not do anything
else (you need other tools to do other
tasks, such as masking, compositing, etc). I consider it to be the
testbed for new code that goes into libpano.

Nona is more refined and is capable of outputting different formats.

PTmender is, I presume, 4-5 times faster than nona.

[hugin-ptx] How to fill black areas of a panorama?

2011-01-04 Thread panhobby
Hi,

I'm now shooting almost only handheld panoramic pictures. One side
effect is the lack of precision while shooting pictures. Then, it
appears sometime that my pictures are not fully covering the area of
the final image. There some parts at the top or the bottom of the
image that are fully black and without information.

In any case, the approach would go threw the following steps:
1) Fill black areas with other parts of the image
2) Blend the addition from the previous step with the image to produce
the final image.

I wonder what is the best approach/tools to execute the second step?
I did some manual tests with a picture editor (photoshop) but, maybe
because of lack of expertire, I didn't succeeded to get an invisible
blend. It seems the lastest version of photoshop elements provide a
function to fill empty part of an image. As anyone experimented that?
I would think that enblend or a similar tool could be used to do the
merge automatically?

Thanks for your help

PH

[hugin-ptx] Re: Hugin coordinate system

2011-01-04 Thread D M German

Hi Joshua,

Sorry I haven't replied to you earlier. Once my email piles up, it takes
some time for me to go over it.

We basically have two translations. The one implemented by Pablo, and
used by Hugin, and the one implemented by Dev and I, which is not
directly available from Hugin.

I don't think we have this well documented, but let me try to explain
you how it works.

Any photo is mapped to the sphere, from the sphere, it is then remapped
to the corresponding output projection. This imposes a big limitation in
linear panoramas: they are not really linear, they are slices of the
sphere.

In a previous message I listed the order in which the remapping
happens. Remember, it is done backwards (any point of the output
projection is mapped back to each point in the source images.

In the panotools model (also used by Nona and Hugin), the center of a
photo is the center of the world, with X and Y in the usual
direction, and normalized according to their field of view and input
projection with respect to the area it would cover in the sphere.

I really don't know the way the Tr[XYZ] parameters work, but the code is
easy to read, and Pablo can probably answer any questions you have:

plane_transfer_from_camera is the inverse, if I remember correctly.

Some notes:

* mp-distance is a used to normalize the distances in the image (to a
  unit sphere).

* the pointer variables are the outputs, and the non-pointers, the
  inputs.

[hugin-ptx] Re: help with Control Point Detector Programs settings

2011-01-04 Thread kevin
Ok I figured out what's going on.  I did a test with less images and
it worked perfectly.  So then I went back to the pano I was working on
and started removing images thinking maybe it was too many in the
row.  I had one stack that it couldn't find any CPs, as soon as I
removed that stack then it ran step 4 from the wiki.  It looks like
the code exits out if not all the images are connected to at least one
other image.  It would seem better to just go ahead and try to do step
3 (alignment for determining overlap) and running step 4 (CP finder
between overlapping imges) even when there is an image or stack that
can't be paired with another image.

Yes, this is how I patch missing areas of sky and ground, you can do 
it all in Hugin.


So for a hole in the sky I would select a photo that is already in 
the project with a lot of sky and add this again to the project 
(you can have the same photo in one project multiple times), but use 
the Crop or Mask tab to remove everything but the sky from this 
image.


Drag it around in the Preview until it covers the hole, but before 
you stitch set the enblend parameters to '-l 29'.


This panorama has the sun (actually my hand shading the sun) and my 
shadow removed using this technique, there has been no 
post-processing or retouching:

The wiki pages can be just a general description.  Usually the

e.g:

   CPClean uses statistical methods to remove wrong control points
   
   Step 1 optimises all images pairs, calculates for each pair mean 
  and standard deviation and removes all control points 
  with error bigger than mean+n*sigma

   Step 2 optimises the whole panorama, calculates mean and standard deviation
  for all control points and removes all control points with error
  bigger than mean+n*sigma
   
 Options:

-o file.pto  Output Hugin PTO file. Default: 'filename_clean.pto'.
-n num   distance factor for checking (default: 2)
-p   do only pairwise optimisation (skip step 2)
-w   do optimise whole panorama (skip step 1)
-h   shows help

This is definitive because this is the bit written by the 
programmer.  If there is more relevant but technical info then it 
could also be in a man page or on the wiki (or both sometimes).

If i'm not mistaken, the -p in cpclean only optimizes each pair of images
according to the standard deviation you specify - if you are still at risk
of removing all CP's between images, right?


No it should only remove some of the points with an error-distance 
greater than the average, you will always have some points left.

The more specific the report the more likely it gets fixed, e.g 
something like this would be good: 
EXIF display shows Aperture and Shutter Speed but not ISO.

Re: [hugin-ptx] How to fill black areas of a panorama?

 Hi,

 I'm now shooting almost only handheld panoramic pictures. One side
 effect is the lack of precision while shooting pictures. Then, it
 appears sometime that my pictures are not fully covering the area of
 the final image. There some parts at the top or the bottom of the
 image that are fully black and without information.

 In any case, the approach would go threw the following steps:
 1) Fill black areas with other parts of the image
 2) Blend the addition from the previous step with the image to produce
 the final image.

 I wonder what is the best approach/tools to execute the second step?
 I did some manual tests with a picture editor (photoshop) but, maybe
 because of lack of expertire, I didn't succeeded to get an invisible
 blend. It seems the lastest version of photoshop elements provide a
 function to fill empty part of an image. As anyone experimented that?
 I would think that enblend or a similar tool could be used to do the
 merge automatically?

 Thanks for your help

http://liquidrescale.wikidot.com/ does a rather good job at filling
smaller areas with missing data.
