Matlab 自带的滤波函数

edge fspecial 打开fspecial文件可以看到例子

%      I = imread(‘cameraman.tif‘);
%      subplot(2,2,1);imshow(I);title(‘Original Image‘);
%      H = fspecial(‘motion‘,20,45);
%      MotionBlur = imfilter(I,H,‘replicate‘);
%      subplot(2,2,2);imshow(MotionBlur);title(‘Motion Blurred Image‘);
%      H = fspecial(‘disk‘,10);
%      blurred = imfilter(I,H,‘replicate‘);
%      subplot(2,2,3);imshow(blurred);title(‘Blurred Image‘);
%      H = fspecial(‘unsharp‘);
%      sharpened = imfilter(I,H,‘replicate‘);
%      subplot(2,2,4);imshow(sharpened);title(‘Sharpened Image‘);

opencv自带的滤波函数

自己实现的滤波函数
