function Image_MAE=MAE(Im_original,Im_modified)

if (size(Im_original)~=size(Im_modified))
    error ('error:image sizes do not agree')
end


[m,n]=size(Im_modified);
A=double(Im_original);
B=double(Im_modified);
sumaDif=0;

%MSE Im_original为原始未经污染的图，Im_modified为去噪后的图
% 均方误差（MSE）
function Image_MSE=MSE(Im_original,Im_modified)

if (size(Im_original)~=size(Im_modified))
    error ('error:image sizes do not agree')
end

[m,n]=size(Im_modified);
A=double(Im_original);
B=double(Im_modified);

window = fspecial('gaussian', 11, 1.5);
I1=imread('go.tif');
I2=imread('go1.tif');
I1=imread('mo_01.png');
I2=imread('mo_02.png');
[mssim, ssim_map] = ssim_index(I1,I2, 0.02, window, 255)
[mssim, ssim_map] = ssim_index('1.jpg','1.jpg', 0.02, window, 255);
K = [0.05 0.05];
window = ones(8);
L = 100;
[mssim ssim_map] = ssim_index(I1, I2, K, window, L);

mssim                        %Gives the mssim value
imshow(max(0, ssim_map).^4)  %Shows the SSIM index map
