PMK_8.m 为八方向的PM—扩散方程

其他函数可参见函数内部的说明

扩散方程主要用来图像去噪，效果较好，能够较好的保留图像的突出边缘，对颜色变化弱的部分能较好的进行去噪平滑-PMK_8.m direction for the eight-PM-diffusion equations can be found in other functions within the function descr iption of diffusion is mainly used to image denoising, better, better able to retain the prominent edge of the image on the weak part of the color change can be more denoise smooth good
