WebWang et al., in their revolutionary work on the structural similarity index or SSIM , argued that human visual perception is highly sensitive to structural information. The SSIM index incorporates luminance, contrast, and structural comparison information and achieves a very good correlation with the mean opinion scores (MOS) of human observers. 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).
