摘要：

The generalized Fourier Transform on a given group is applied to invariant feature extraction in the case of a gray-level image. Thus, a new complete and convergent set of invariant features under planar similarities is proposed using the Analytical Fourier-Mellin Transform (AFMT). So, this set gives a distance between the shapes which is invariant under similarities.
