<div dir="ltr"><div>Hello everyone, </div><div><br></div><div>Either I am missing something or the write up about the elongation is not matching the actual implementation. </div><div><br></div><div>"elongation is computed as the ratio of the largest principal moment by the smallest principal moment. "</div>
<div><br></div><div>however in itkShapeLabelMapFilter.hxx elongation is defined as largest principal moment / second largest principal moment. In 3D the definition and the implementation becomes inconsistent. </div><div><br>
</div><div>from itkShapeLabelMapFilter.hxx </div><div>331 elongation = vcl_sqrt(principalMoments[ImageDimension - 1] / principalMoments[ImageDimension - 2]);</div><div>332 flatness = vcl_sqrt(principalMoments[1] / principalMoments[0]);</div>
