中值濾波+均值濾波，matlab代碼

用的圖檔：rgb圖像

直接可以運作。

程式：

close all
clear 
clc
src_image = imread('1.bmp');
image = rgb2gray(src_image);
[m, n] = size(image);
%模闆大小
k = 3;
myFilter = zeros(k, k, 'uint8');
for i = 1 : k
    for j = 1 : k
        myFilter(i, j) = 1;
    end
end
[image2, image3] = spacelFilter(image, myFilter);
image4 = medfilt2(image, [3 3]);
figure(1)
imshow(image), title('原圖像');
figure(2)
imshow(image2), title('3*3均值濾波圖像');
saveas(2,'均值.bmp');
figure(3)
imshow(image3), title('3*3中值濾波圖像');
saveas(3,'中值.bmp');
figure(4)
imshow(image4), title('matlab自帶的中值濾波圖像');
saveas(4,'m中值.bmp');
