I came across PSNR and SSIM metrics to measure filter quality but could not fully understand what the values mean. Can anybody help me about: Does a higher PSNR value means higher quality smoothing (getting rid of noise)? Should SSIM value be close to 1 in order to have high quality smoothing?

Sep 30, 2015 · SSIM is an algorithm for estimating the perceived quality of an image or video. Its computational simplicity and ability to accurately predict human assessment of visual quality has made it a standard tool throughout the television industry in broadcast and post-production houses — where, among other uses, it serves as a guide for how much or how little videos should be compressed while they are being transmitted.
