computes WPSNR (weighted peak signal-to-noise ratio) between two images in decibels (dB).

WPSNR: Weight Peak Signal to Noise Ratio-WPSNR: Weight Peak Signal to Noise Ratio

This function displays the PSNR (peak signal-to-noise ratio) between two images. The answer is in decibels (dB). PSNR is very common in image processing. A sample use is in the comparison between an original image and a coded/decoded image. Typica
