代码描述

中文说明:这个文件是关于分数阶余弦变换的MATLAB代码和分数阶傅里叶变换MATLAB代码,可以用于图像处理加密、滤波等用途,一维的变换实测在即接近整数时会有较大差距,可能算法比较旧,二维的变换没用过,可能和一维的由类似的问题,如果有需要的可试一下,最近我在做关于分数阶傅里叶变换的工作,希望能够交流一下


English Description:

This file is about the fractional cosine transform matlab code and fractional Fourier transform matlab code, can be used for image processing encryption, filtering and other purposes, one-dimensional transformation measurement will be close to the integer there will be a big gap, the algorithm may be relatively old, two-dimensional transformation has not been used, and one-dimensional transformation may be caused by similar problems, if you need to try, I recently in Do on the fractional Fourier transform work, hope to be able to exchange
