Abstract

The importance of phase and amplitude in the field of image processing is compared by using the method of Fourier transform. The digital image is encoded with only-phase encode and the computer simulation results are given. The research shows that phase is more important than the amplitude, and phase-only code of image is effective for image encryption and we should make full use ofthe phase of the image.
