随机生长模型，用以模拟多孔介质的孔隙结构，根据不同参数，主要是孔隙率的改变，生成不同孔结构-porous medium simulation

matlab对图像随机添加四种噪声，然后分别通过自编中值滤波，均值滤波，高斯滤波，和维纳滤波进行滤波-matlab add four random noise to the image, and then were filtered by self median filtering, mean filtering, Gaussian filtering, and Wiener filtering

此程序用来在MATLAB中创建泰森多边形，并且在产生随机中心点的同时，各中心点必须满足特定的距离关系，最后输出中心点坐标以及相应的顶点坐标，以在ABAQUS中建模。-This procedure is used in MATLAB create Thiessen polygons, and at the same time generating random center point, each center must meet specific distance relationship, t

Matlab实现的BM3D去噪算法，对随机噪声去除效果较好，如果没有指定输入图片，将对自带的示例图片去噪并显示结果。-Matlab to achieve the BM3D denoising algorithm, the random noise removal effect is better, if not specified input picture, will bring the sample image denoising and display the results.
