HVS的许多特性都与图像质量的评价相关，由于HVS非常复杂,Zhou Wang认为，自然图像信号是高度结构化的，图像的像素间有很强的相关性。构信息提取的图像质量评价构相似性理论是因此提出了一种关于图像质量评价的新思想。-HVS in many of the features are relevant to the evaluation of image quality, the HVS is very complex, Zhou, Wang believes that the natural image signals are highly structured, between pixels of the image there is a strong correlation. Structure similar to the structure information extracted image quality assessment theory is therefore proposed a new thinking on the image quality assessment.
