Hi,
I am trying to calculate curvature value for each pixel in an image.
I could not find a function in ITK.
I used RecursiveGaussianImageFilter to find first and second derivatives.
Then I put them in to this formula
k = (x'y'' - y'x'') / (x'2 + y'2)3/2
but, results are not good..
Do you have a function to calculate curvature by using ITK functions?
Or do you have any suggestion?
Thanks
