<div>Seth,</div>
<div><br>
</div>
<div>Registration is done in PHYSICAL space, not pixel space. I think the problems you are running into </div>
<div><br>
</div>
<div>PhysicalSpace = DirectionCos*Spacing*PixelIndex+Origin</div>
<div><br>
</div>
<div>The previous bug is that “Spacing” was not being interpreted properly for JPEG images. Based on your image, it appears as if perhaps you now have an “origin” adding problem.</div>

<br>
<div dir="ltr">You'll have to forgive me; I'm a video editor by trade and have been at a steep learning curve to get this far into the troubleshooting. Let me make sure I understand. Essentially, the disparate ppi's in my images are causing my issue. If, just
by example, all of my images were set to the same ppi, things should work correctly. My use of JPEGs caused the difference of outputs that I was interpreting as correct behavior.<br>
<br>
Assuming this is the concept, I went back and ran a test from my original TIF images (they're in the 100MB range so I wasn't using them before). I changed everything to 72 ppi in Photoshop without resampling so that every image had the same dimensions as before,
then ran LandmarkWarping2 again. This time, 4.3.2 and 4.4.0 did produce the same output, but it didn't produce a correct output, at least not how I understand Landmark Warping should work. This is what that output yielded: <a href="https://dl.dropboxusercontent.com/u/13015285/Chad-4.4.0-005.jpg" target="_blank">https://dl.dropboxusercontent.com/u/13015285/Chad-4.4.0-005.jpg</a>
(Note: This is a jpeg made from the output tif, just to cut down on filesize).<br>
<br>
It seems as if the output is at the appropriate scale, but it obviously is not in the expected spot. Am I just missing something in the concept of landmark warping, did I not understand that voxel spacing concept, or is there something else going on?<br>
<br>
Thank you all so much for your help. I'm going to try the suggested "SetOutputParameters" change, too, to see what happens.</div>

<div>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.</div>

</div>
<div><br>
</div>
<div>For the resampling stage of the output you are propagating the input image voxel counts, but not the input image voxel spacings.</div>
<div><br>
</div>
<div>My guess is that you want to use "SetOutputParametersFromImage(const ImageBaseType *image);" and pass the input image for your call to the "itk::ResampleImageFilter".</div>
<div><br>
</div>
<div>This will result in an output image with the same pixels/inch as your input image.</div>

<div dir="ltr">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.
<div><br>
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.<br>
<br>
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).</div>
