Paper Abstract

Fourier processing method is very popular in signal and image analysis. In this paper, a generalized Fourier transform (GFT) processor is introduced. It is generalized in that it contains the conventional Fourier transform (CFT) processor as a very limited special case by extending the diagonal filter matrix in CFT to a nondiagonal one. Thus, obviously, the GFT processor should be more powerful than the CFT processor. A computer demonstration shows this.
