[hugin-ptx] [bug#678842] Stitcher canvas size, proportional change not bidirectional

2011-03-31 Thread Neeraj Gupta
Hi,
I was looking at this[https://bugs.launchpad.net/hugin/+bug/678842 ]
particular bug description :

*Changing the horizontal canvas size in the Stitcher results in a
corresponding proportional vertical canvas size just as would be expected.
The same is not true when changing the vertical canvas size. A vertical
canvas size change does not change the horizontal canvas size and in fact
appears to function as a crop.*

I have two questions:-
1. Is it really a bug? (read details below).
2. If yes, then please give suggestions how I should rectify it.

Initially after looking at Panopanel.cpp[1] file especially function at
Canvas Width and Height events(Line 73,74) and then looked for their
respective functions i.e. WidthChange[2] and HeightChange[3], I thought
there is just a typo in line 686(inside Height()) as it seemed that the
author missed to include m_KeepViewOnResize as its present in WidthChange
funtion), but build gave invalid parameter error for HeightChange funtion.

So, I looked for their declaration and there I saw that the original author
has coded it that way( I am assuming that he meant to do it in this way only
as it does seems to be *just missed it* case.).
Please see the definitions of HuginBase::PanoramaOptions::setWidth[4] and
SetHeight[5].

If it needs to be modified, then please suggest me what formula's and
condition should I use to modify the horizontal canvas size as I don't have
much knowledge of this

Regards

Neeraj

2011-03-31 Thread Bruno Postle
Yes it is necessary to be able to change vertical field of view
independently of horizontal field of view - this is the only way to change
the panorama aspect ratio. If there is a bug it is that both sliders should
be completely independent.

Yeah, but it would have been of mediocre quality at best.

RAW processing is out of scope of hugin and if it was implemented it
would be something as simple as using dcraw to load an image. Nobody
(hyperbole) uses dcraw to process their RAWs, because it's too simple
to be useful alone. We couldn't compete with applications like
Lightroom, Aperture or Rawtherapee. It would probably take a few man
years to get there.

Re: [hugin-ptx] [REVIEW] Pushing Hugin changes to VIGRA upstream – Hugin changes

2011-03-31 Thread Lukáš Jirkovský

 Hello Yuv,
 I'm not yet convinced it's a good thing to do at this point in time.
 Still the users would have to manually apply several patches to VIGRA
 unless there's a public clone of VIGRA with changes applied so
 applying one more patch doesn't really hurt anything.

 I plan to send the patches upstream on Thursday or Friday, so we may
 find out whether the changes to hugin doesn't go in vain quite soon.

 Lukas


The changes to VIGRA were all accepted upstream. I pushed the branch
system_vigra which contains the changes necessary to use the system
wide installation of VIGRA. It needs the VIGRA from the VIGRA
mercurial repository [1] to compile.

At this point everything works with the exception of hugin_hdrmerge.
Hugin_hdrmerge depends on some of the VIGRA internals and I'm not sure
how to fix it. Also I had to remove the use of ImageCache in the
deghosting implementation.

Enjoy,
Lukas

Nice work! 

I've been working on getting Hugin to cross-compile from Linux to Windows in 
my precious spare time, and the stock vigra lib already compiles, so this 
will definitely help! There are still a few packages missing in the 
cross-compiling system I'm using (mingw-cross-env [0]), I'd have to check 
which ones, but I hope that in the end I'll be able to do a full 
cross-compile. This will make the process of releasing Windows binaries even 
easier (at least for me). Note that I *really don't* have that much spare 
time, so it may take a while. Of course anyone interested may take a look as 
well, we're talking open source here :)

Has anyone studied smartblend verbose output to figure out how it works?

It is vastly superior to enblend (in terms of seam placement). And it's old, 
crusty, closed-source, and definitely not going to be updated again.

This to me is one of the biggest drawbacks to the hugin collection of 
software.

I had a look at his, too. However, without being able to actually use
the resulting binaries due to my lack of a windows license and my lack
of interest to get one, I figured that I won't be able to support this
kind of port. On the other side, if I had a windows license and would be
willing to create panos on this platform, wouldn't it be more natural to
use the (available) free MS development tools for porting?

I think that hugin needs to attract some more windows users being able
to fend for their OS themselves. Providing binaries that are not tested
by the producer and that can not be properly supported, therefore, does
not help.

Sorry, just my 2 cents.

Hello Michael,

It's been almost 2 years since we were last in touch. I imagine you have 
been very busy. Is there any news on the Smartblend sources and/or any 
further development?
Out of curiosity: what other projects are you involved in? Anything 
image-related? I found out that you used to have a website about Smartblend, 
but it has been turned into one of these annoyingly useless search page 
sites by some domain scraper, unfortunately.
Hope to hear from you soon.

  I've been working on getting Hugin to cross-compile from Linux to
  Windows in my precious spare time, and the stock vigra lib already
  compiles, so this will definitely help!

 I had a look at his, too. However, without being able to actually use
 the resulting binaries due to my lack of a windows license and my lack
 of interest to get one, I figured that I won't be able to support this
 kind of port. On the other side, if I had a windows license and would be
 willing to create panos on this platform, wouldn't it be more natural to
 use the (available) free MS development tools for porting?

I understand your situation, but from my point of view, compiling under 
Linux is usually a bliss. I like the way things can be automated using the 
shell in Linux. And this mingw-cross-env thing really takes away a lot of 
pain. For instance, I can build the required libs (minus some that I still 
need to add) using a single make command. The system will automatically 
download the sources for me, including dependencies, and build everything 
into static libs. The only thing left to do then is to compile Hugin (and 
Enblend, APSCpp, ...) itself, using cmake and some cross-compiling settings. 
Pretty easy. I'm using a virtual machine to do this.

On the other hand, using the MS path requires many more steps. A whole lot 
of packages need to be compiled separately. Just take a look at [0] to see 
what I mean. Ok, if your initial setup is done (building dependencies), 
building and rebuilding Hugin is not a problem, except when some dependency 
needs a rebuild...

To me, the Linux approach is much simpler. And if the workflow has been 
setup correctly, Hugin can be built on a (native) Linux machine, QA tested 
by a few Windows pre-testers, and then distributed.

 I think that hugin needs to attract some more windows users being able
 to fend for their OS themselves. Providing binaries that are not tested
 by the producer and that can not be properly supported, therefore, does
 not help.

I agree about quality assurance. Distributing non-tested binaries is not a 
good thing. But this kind of testing has to be done for native Windows 
builds (built on a Windows machine I mean) as well, and depending on the 
builder, this will happen or not.
 

 Sorry, just my 2 cents.

No apologies required, your points are valid.

[hugin-ptx] Re: enfuse for tonemapping of a single RAW

2011-03-31 Thread Erik Krause

Am 31.03.2011 20:57, schrieb Jeffrey Martin:

well, there are tons of raw developing programs that use dcraw.


Most raw developing programs use dcraw code to read and decode raw 
files, but very few actually use the dcraw post processing. There are 
better highlight recovery algorithms, there are far better 
interpolators, better white balance techniques, denoising and so on. 
dcraw even treats the camera orientation sensor differently on some 
cameras (it uses maker notes instead of EXIF) and it delivers a 
different image size.


As I wrote before: A shell script to create three temporary files by 
varying the dcraw -b parameter and a subsequent enfuse will provide you 
with the desired functionality.

And all patches have been accepted! I'm still working on some tests,

wide installation of VIGRA.


Lukáš, thanks for doing this, it has been needed for a long time.

Regarding fixing the Hugin sources, there is no need to remove the 
Hugin copy of the library from the sources if it is possible to 
build with the system library as an option.  vigra now has a 
vigra-config tool which gives output similar to pkg-config, so it 
should be possible for cmake to detect if the system vigra is  
1.7.1

Is there a valid point in keeping a local copy of a library if the official 
one works? If you mean keeping the local copy until the changes are in a 
release version of Vigra, I can understand, but otherwise?

Yes and no, it can't be removed until there is a vigra release, but 
we don't know when this will be.  Also the pressure from Linux 
distributions is for binary packages to use system libraries, they 
don't care what unused cruft is in the Hugin tarball.


If the latest vigra happens to fix any of the longstanding bugs that 
keep getting reported in the hugin/enblend trackers then it could 
even be worth updating the vigra code in hugin/enblend.
