ref = imread('6.jpg'); imshow(ref) A = imnoise(ref,'salt & pepper', 0.02); imshow(A) err = immse(A, ref); fprintf('\n The mean-squared error is %0.4f\n', err);

在 MATLAB Online 中打开

ref=imread('test.jpg');  % Change the image Name
figure, imshow(ref), title('Input Image');
A=imnoise(ref,'salt & pepper', 0.02);
figure,imshow(A), title('InputImage with Noise'); 
err=immse(A,ref); 
fprintf('\n The mean-squared error is %0.4f\n',err);
