用Arnold矩阵变换进行图像置乱的加密算法及其源代码(By Arnold transform the matrix of image scrambling encryption algorithm and its source code)

这是数学建模中会用到的各种算法的总结书，内容很好，希望能有所帮助。(This is the mathematical modeling will be used in a variety of algorithms summarize the book, the content well, hoping to help.)

in this folder contains the import the picture and how to find the effects. how to read the image and how to show the images.

采用二维中值滤波函数medfilt2对受椒盐噪声干扰的图像滤波(2D median filtering function medfilt2 right by the Salt and Pepper noise image filtering)

自己调试的GSO程序，简单可运行，适合初学者参考。(The glowworm swarm optimization (GSO) is a swarm intelligence optimization algorithm developed based on the behaviour of glowworms (also known as fireflies or lightning bugs). The behaviour pattern of glowworms which is used for this algorithm is the apparent capability of the glowworms to change the intensity of the luciferin emission and thus appear to glow at different intensities.)
