[Insight-users] Help - ImageMomentsCalculator Error

[Dan Mueller]

Hi Fauze,

This typically occurs when the input image is black -- all zeros (see
Code/Algorithms/itkImageMomentsCalculator.txx at 151-155). I guess it can
also occur when using a signed image, and all of the pixels add to
zero.

Confirm that the image you are passing the moment calculator has been
correctly read/processed.

HTH

Cheers, Dan
