在频域的基础上对图像进行滤波，带通，带阻，高通，低通-In the frequency domain on the basis of image filtering, band pass, band stop, high-pass, low-pass

首先，将图片进行分割处理； 然后，用均值滤波对每个分割部分进行降噪处理。 从而提高图片的质量。-First, the image segmentation processing Then, mean filtering for noise reduction processing for each divided part. Thereby improving the quality of the picture.

中值滤波代码，可以有效消除图像拼接中的接缝-Median filtering code, can effectively eliminate image stitching in the seams

一个很好的滤波器设计算法，包含了源代码、测试图像等，对于学习图像处理的同学很有帮助-A good filter design algorithms, including source code, test images, image processing for learning helps students
