<br><div>Hi,</div><div><br></div><div>A program that was working with ITK 3.14 is not working with 3.16 (on OSX). It's a mystery to me.</div><div><br></div><div>The program takes a list of image files (regex input), scans them all for the largest image dimensions (2D), then "converts" or resamples all the images in the series into the same dimensions.</div>
<div><br></div><div>The conversion process involves an information filter and a reslicer. The latter includes an affine transform (just a translation to center the images) and an interpolator.</div><div><br></div><div>The outputs fail to replicate the intensity scale of the inputs. Also, the outputs are wildly different for .png and .tif inputs.</div>
<div><br></div><div>All the code and example files are available for download (as of Feb 2010)</div><div><a href="ftp://anonymous">ftp://anonymous</a>@<a href="http://ftp.buckinstitute.org/dweber/testResize.tgz">ftp.buckinstitute.org/dweber/testResize.tgz</a></div>
<div><br></div><div>In that archive, the source code and a build are in testResizeCode, the input data files are in testResize/w1/bw/ and the outputs are in testResize/w1/bw_resize. There is a script, testResize.bash, to run the example - it has a variable for image type (png or tif). The output files are wildly different for the png and tif inputs.</div>
<div><br></div><div>BTW, the purpose of this image resize process is to provide a series of images with the same dimensions for registration. Is it true that a registration process for any two images must have images of the same dimensions?</div>
<div><br></div><div>Take care,</div><div>Darren</div><div><br></div>
