[Insight-users] Hu moments with itkImageMomentsCalculator

[Moti Freiman]

Hello,

I want to compute the Hu moments of a 2D image.

For that  i need to compute the zero, first, second and third order 
moments of the image.

I found the class itkImageMomentsCalculator, but it provides just part 
of the required moments.

In addition, I got confused when trying to understand what the matrix 
returned by the function:

GetCentralMoments (), includes.

Does it include the u02, u20, u21, u12 moments, and in which order?

Then, how can i get the u11 central moment and the third order moments?

Thanks,

Moti
