Kaiwen Zhang, Shuozhong Wang, Xinpeng Zhang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2002
In this paper, an image quality measure, termed pixel-based correlation weighted-mean square error (WMSE), is presented. The proposed distortion measure depends not only on the mean square error in the distorted image, but also on correlation between pixels in a predefined neighborhood. Experimental results are given to show the advantage of the described method.
