Hello,

It is known that the Fourier transform can be used to compute the similarity between two images, and using the Fourier-Mellin transform one can also compute transformations (translation, scale, and rotation) between images. But I think that if the object is occluded (a part is truncated or hidden by another object) this transform won't give good results to match two objects.

So my question is about the robustness of Fourier Transform to occlusions, is there a way to do that, if this is the case is there a Matlab implementation?

It would nice from you to help me because I am trying to compute the similarity between two images, and I tried the Fourier Mellin transform applying rotation, scale, translation and that was working fine but when I have occlusions it doesn't work.
