Dear ITK users,<br><br>I'm having some trouble with itk::Statistics::ScalarImageToGreyLevelCooccurrenceMatrixGenerator.<br><br>Please see the code at the following pastebin address: <a href="http://pastebin.com/m2f534d31">http://pastebin.com/m2f534d31</a><br>
<br>Everything in "Part 1" seems to be running correctly, and if I insert a call to reader->Update() at the end, the image is read correctly and I get no errors. However, the currently uncommented code is throwing a segfault, specifically at the highlighted line (#53). As the comment says, I suspect the problem is that I need to update the pipeline somewhere before I can call ->Compute(), but I can't figure out where.<br>
<br>If it helps to have a general idea of what I'm doing, I'm trying to use the above code (include the section at the end that is currently commented out) to generate texture features of a 3D image. Generating the scalar measure of entropy for the entire 3D image is just an initial test. If that succeeds, I hope to adapt the code to be used with a NeighborhoodIterator to get the texture measures around each of the voxels in the image, eventually giving a 3D output image. In ITK terminology, I think what I'm going for is a kind of "texture filter." Any general suggestions for that project are, of course, always appreciated as well.<br>
<br>Thanks very much,<br>Marshall <br><br><br clear="all"><br>-- <br>Marshall Strother<br>Washington University in St. Louis<br>
