- 自己现在在做的论文用到灰度共生矩阵,找了好久都没找到很好用的,所以自己就编了个,不很完美,但绝对可用,已经实现过。包括灰度共生矩阵的生成以及一些特征参数。f1,二阶距。f2,对比度。f3,相关。f5,逆差距。f6,和平均。f7,和方差。f9,差平均。f10,差方差。请不吝赐教。,Now do their own papers in the gray co-occurrence matrix used to find for a long time to find no good use, so

- nsf5隐写算法,DCT的升级版,MATLAB实现,可以抵抗一般的DCT隐写分析(The algorithm nsF5 evolved from the F5 algorithm originally proposed by Andreas Westfeld in 2001. F5 decreases the absolute value of DCT coefficients and incorporates matrix embedding - a coding scheme that de
