Title: Influence of the Smooth Region on the Structural Similarity Index
Abstract: The Structural Similarity (SSIM) Index is a very popular image quality assessment algorithm due to its good performance and simple calculation. This paper analyzes the influence of the smooth region on the performance of SSIM. It was found out that SSIM tends to depend on the quality of the smooth region to assess the quality of the whole image. From analysis by means of the SSIM quality map, we found out that SSIM overestimated the importance of the smooth region to visual quality. So in this paper we proposed a new weighting function as the spatial pooling method. The resultant weighted-SSIM outperforms the classic SSIM by a considerable amount.
