WebInformation content weighted structural similarity measure (IW-SSIM) is an extension of the structural similarity (SSIM) index by incorporating the idea of information content weighted pooling. The same idea can also be applied to peak signal-to-noise ratio (PSNR), leading to an information content weighted PSNR (IW-PSNR).
