    58 Therefore, I believe that a correction factor should be included in the final formula to eliminate the 3dB increase depending on the bit-depth chosen, and thus obtain the same "or very similar" WPSNR quality value, as is the case with the other metrics. Now the question is: what is the "correct" WPSNR value? ¿33.9514, 36.9617, 39.9720, other...?
