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.
