1、用 matlab 实现多幅图像平均去高斯白噪声.
源代码
clear
x=imread('1.jpg');
figure;
imshow(uint8(x));
[m,n]=size(x);
L2=zeros(m,n);
for a=1:15
noise=randn(m,n)*35;
L1=double(x)+noise;
L1=uint8(L1);
L2=L2+double(L1);
end
L2=L2/a;
L3=zeros(m,n);
for b=1:30
noise=randn(m,n)*35;
L1=double(x)+noise;
L1=uint8(L1);
L3=L3+double(L1);
end
L3=L3/b;
figure;
imshow(uint8(L1));
figure;
imshow(uint8(L2));
figure;
imshow(uint8(L3));
