Zhou Wang proposed a new idea of Structural Similarity Index (SSIM )for image quality measurement based on the assumption that the HVS is highly adapted to extract structural information from the viewing field. The Mean Structural Similarity Index (MSSIM) contains three parts: Luminance Comparison l(x, y), Contrast Comparison c(x, y) and Structure Comparison s(x, y).
