Hi Dav <br><br>There is a class hierarchy in ANTS ( <a href="http://www.picsl.upenn.edu/ANTS/">http://www.picsl.upenn.edu/ANTS/</a> ) that computes either mesh or image curvature using this method : <a href="http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.103.1296">http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.103.1296</a> ... I was using these tools recently to test some clinical hypotheses and the results were reasonable. If you compile ANTS then you'll get an executable that can be used as follows:<br>
<br>SurfaceCurvature BrainIn.nii BrainOut.nii 3 0 <br><br>where 0 means compute mean curvature and 3 is the sigma of a gaussian derivative operator. <br><br>The classes are itk-compatible, as far as i know. <br><br>
