Luis: THANK YOU FOR LOOKING INTO THIS!
Seth: I think you were depending on a "bug" in the JPEGIO code to get the desired behavior you wanted.
===============
As an experiment, if you convert each of your images to tif format and run the 4.3.2 version of the code, you will have consistent results with both ITK4.3.2 and ITK4.4.0.
1-StaticImage.jpg* <-- 5412 × 7216 pixels, 304.79 pixels/inch
2-MovingImage.jpg* <-- 4800 × 5434 pixels, 72 pixels/inch
LandmarkWarped-ITK4.3.2.jpg <-- 5412 × 7216 pixels, 72 pixels/inch
LandmarkWarped-ITK4.4.0.jpg <-- 5412 × 7216 pixels, 72 pixels/inch
For the resampling stage of the output you are propagating the input image voxel counts, but not the input image voxel spacings.
My guess is that you want to use "SetOutputParametersFromImage(const ImageBaseType *image);" and pass the input image for your call to the "itk::ResampleImageFilter".
This will result in an output image with the same pixels/inch as your input image.

Hans,
Here is what I found:
aleph $ git bisect bad
Bisecting: 0 revisions left to test after this (roughly 0 steps)
[b7c71079a70b33a4018e132b31ee2fc0a36b8129] ENH: JPEG IO now writes and reads spacing, similar to the TIFF IO (ITK-3023)
aleph $ git log --oneline -1
b7c7107 ENH: JPEG IO now writes and reads spacing, similar to the TIFF IO (ITK-3023)
aleph $ git bisect bad
b7c71079a70b33a4018e132b31ee2fc0a36b8129 is the first bad commit

So, it seems that the problem is not with the Landmark Deformation itself,
but
with the fact that we now put spacing information in the resulting output jpg image.

Hans,
I'm playing with the git bisect, while I sit in long meetings...
I'm making progress (5 steps to go).
Will let you know how far I get.
Thanks

Seth,
We discussed this at our t-con this morning. I'll try to look at it this weekend.

I had to rebuild ITK as I don't think the tests were built unless I also included the cmake flag ITK_BUILD_ALL_MODULES. Maybe not. Anyway, I ran the LandmarkWarping test and it reported that it passed. I would be inclined to think that there was something just wrong with my landmarks file if it weren't for the fact that the exact same file produces expected results on an older version.

Hi Seth,
To run the test associated with the examples, set
BUILD_EXAMPLES ON
in the ITK CMake configuration, build, and run
ctest -R LandmarkWarping
on the command line in the ITK build directory.
Thanks,
Matt

Ok, so a couple of updates. First, I checked and I had tested on Ubuntu 13.04 (Raring Ringtail) and had compiled using GCC 4.7.3. ITK 4.4.0 gave me the same issues with LandmarkWarping2 as on OSX.
On OSX, I had never noticed that Xcode's gcc was using an llvm backend. Clang is supposedly the same way. Also, I've already update all of our computers to OSX 10.9 as we hardly ever do any ITK or development work, so going back to Mountain Lion isn't really an option. However, I did spend today compiling GNU GCC (4.8.2) on my machine and I recompiled ITK 4.4.0 using it instead of Xcode's "GCC". After a successful build, it also exhibits the same issue with LandmarkWarping2. I'm not sure of other variables, but I think it's safe to assume this isn't a compiler issue.
In terms of using the built-in tests, I can find one LandmarkWarping2Test.png under the testing data, but I'm unclear on which of the other images I should register it against (or against it).

Hello,
I am just curious if it's a compiler issue or one with the code.
It's been a while since there has been a bonified version of GNU GCC with Xcode. I am running OS 10.8.5, check this out:
$ /usr/bin/gcc -v
Using built-in specs.
Target: i686-apple-darwin11
Configured with: /private/var/tmp/llvmgcc42/llvmgcc42-2336.11~182/src/configure --disable-checking --enable-werror --prefix=/Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2 --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-prefix=llvm- --program-transform-name=/^[cg][^.-]*$/s/$/-4.2/ --with-slibdir=/usr/lib --build=i686-apple-darwin11 --enable-llvm=/private/var/tmp/llvmgcc42/llvmgcc42-2336.11~182/dst-llvmCore/Developer/usr/local --program-prefix=i686-apple-darwin11- --host=x86_64-apple-darwin11 --target=i686-apple-darwin11 --with-gxx-include-dir=/usr/include/c++/4.2.1
Thread model: posix
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
That is llvm masquerading as gcc.
There is also clang as an option. I'd give that a try. Upgrading to Macericks is going to another set of problems.
Check out the information here:
http://public.kitware.com/pipermail/community/2013-November/000188.html
This may be a good opportunity to run git-bisect, if the issue can be reproduced.

I did try on Ubuntu (Raring Ringtail). It's been a while for Ubuntu, but I believe I used gcc for it. Definitely gcc on OSX. I haven't tried recompiling since upgrading to Mavericks, but I was running Mountain Lion before and Xcode 4.6.
It hadn't occurred to me to check the built-in examples. I should be able to test that tomorrow.

Hello,
Have you tried other systems? Linux perhaps?
What compiler are you using? What OS? What XCode version?
Is this issue reproducible with a test or example already in ITK?
Thanks,
Brad

Was attempting to use ITK-4.4.0 LandmarkWarping2 on OSX and was getting completely incorrect results. The moving image was roughly in the correct spot of the first landmark, but was at a completely incorrect scale. I reverted to 4.3.2 and had no issues at all. I'm fine using 4.3.2, but thought I would mention it here in case anyone has a solution or pointer.
You can download examples of the input and output files here: https://dl.dropboxusercontent.com/u/13015285/LandmarkWarping.zip
