As Image Analyst already told you in https://www.mathworks.com/matlabcentral/answers/231932-is-this-how-to-calculate-mean-square-error-for-two-images#comment_1320422

Look up "image quality metrics" in the help. You'll find functions such as brisque, niqe, piqe, ssim, psnr, immse, multissim, and multissim3. We don't know which would work best for you. Read about them and decide which you think would work best for you.

Thank you. Is any code and theory for implementing the bicubic interpoplation.

where I can get the theory related to this code(that is equations). Becouse theory is required to understand this code.

explanation and code is not matching. where can I get explanation of the code.

you can ask in the Question. The author, Robert, has been on this month, still active.

I do not know what sources he used.
