结合分数傅立叶变换及区域移位法进行图像编码

The Methods of Image Encryption Using Fractional Fourier Transform and Region Shifting Encode

提出了图像区域移位编码算法,并结合分数傅立叶变换,实现了对图像的多重加密编码.计算机模拟表明该编码方法自由度大,保密性强.

An algorithm of image region shifting encode is proposed. Combing it and fractional Fourier transform, multi-channel image encryption encode is implemented. The results of computer simulation show that this method is flexible in the range freedom and strong in secrecy.
