  • Abstract
    Encryption of digital image processing becomes more and more important for Internet data transportation, and many methods can be applied for the processing. In this paper we first introduce how to use matrix algorithm to calculate discrete fractional Fourier transform (DFrFT). And then the fractional Fourier transform (FrFT) is applied to an image encryption and decryption. The matrix algorithm of fractional Fourier transform is implemented in MatLab® 2007.
