Edge-weighted Structural Similarity Index
Jianqiu Zhang · Jisuanji gongcheng · 2011
This paper proposes an Edge-weighted Structural Similarity Index(EWSSIM),which can match well with Human Vision System(HVS).Structural Similarity Image quality assessment(SSIM) does not evaluate highly blurred and Gaussian white noise distorted images well.EWSSIM assigns different weights to contour correlation and local texture correlation of the original image and distorted image,which can represent structural similarity better than SSIM.Experimental results of LIVE image database indicate that the proposed index outperforms SSIM in blurred and Gaussian white noise distorted images and also gives a better coherent evaluation for all kinds of distortions in LIVE database.
