opencv写的同态滤波，高通滤波器采用的是高斯高通滤波器-opencv written by homomorphic filtering, high-pass filter uses Gaussian high-pass filter

基于opencv的同态滤波功能实现，方便简单易懂-Based on homomorphic filtering function of opencv, convenient and easy to understand

自己写的一个同态滤波程序，效果不错，可以-himself in a state with the filtering process and the results were still good, s-A homomorphic filtering to write their own program, good results can-himself in a state with the filtering process and the results were still good,

同态滤波去噪，把频率过滤和灰度变换结合起来的一种图像处理方法，它依靠图像的照度/ 反射率模型作为频域处理的基础，利用压缩亮度范围和增强对比度来改善图像的质量。使用这种方法可以使图像处理符合人眼对于亮度响应的非线性特性，避免了直接对图像进行傅立叶变换处理的失真。-Homomorphic filtering noise, the frequency filter and the gradation conversion processing method combining an image, wh
