No evaluation code

The standard evaluation code is of extraordinary significance to the community. Can you provide evaluation codes for the following indicators? Looking forward to your reply.

For SSIM and PSNR computation, we used Matlab built-in psnr and ssim functions (for example psnr(image1, image 2) and ssim(image1, image2). You can also refer to here https://ww2.mathworks.cn/matlabcentral/fileexchange/64151-structure-similarity-ssim-and-psnr?s_tid=FX_rc2_behav.

For accuracy and BER computation, please refer to some shadow detection works such as https://github.com/xw-hu/CUHK-Shadow#cuhk-shadow-evaluation

Thank you very much for your reply. In SHIQ dataset, are the PSNR=34.13 and SSIM=0.86 in your paper calculated as follows?

for i = 1 : img_num
    i
    
    image1 = imread([testfnlist_gt{i}]);
    image2  = imread([testfnlist{i}]);
    
    psnr_ = getPSNR(image1,image2);
    ssim_ = getMSSIM(image1,image2);
    
    psnr_list(i,1) = psnr_;
    ssim_list(i,1) = ssim_;
end

psnr_mean = mean(psnr_list);
ssim_mean = mean(ssim_list);
