这是我在学习matlab时写的一些简单的图形处理的例子,初学者可以看一下!

I=imread('eight.tif');
I1=imnoise(I,'gaussian',0,0.005);
I2=imnoise(I,'gaussian',0,0.005);
I3=imnoise(I,'gaussian',0,0.005);
I4=imnoise(I,'gaussian',0,0.005);
K=imlincomb(0.25,I1,0.25,I2,0.25,I3,0.25,I4);
figure;
imshow(I);
figure;
imshow(I1);
figure;
imshow(K,[]);
K=double(K);
m=max(max(K));
n=min(min(K));
K=uint8((K-n).*255/(m-n));
imwrite(I,'eightcoin.bmp','bmp');
imwrite(I1,'eightcoin_noised.bmp','bmp');
imwrite(K,'eightcoin_denoised.bmp','bmp');
