摘要：针对人眼对不同图像纹理的敏感差异，提出了一种抗模糊失真的加权结构相似度(WSSIM)图像质量评价方法，它通过提取人眼敏感的边缘信息，将图像分割成不同区域，进行加权处理，获得加权结构相似度(WSSIM)，解决了SSIM对于严重模糊图像的评价问题。在LIVE图库中的高斯模糊库（Gaussian_Blur）与PSNR，SSIM，多尺度结构相似度(MS_SSIM)进行仿真比较。实验结果表明，WSSIM模型计算简单，评价性能远远优于前两种方法而略优于MS_SSIM。

Abstract: Considering different texture has different sensitivity for human eyes, a blur insensitive structural similarity model(WSSIM) was proposed, which based on edge to partition different weight region. Experimental comparisons with PSNR, SSIM and MS_SSIM on the LIVE database show that this appoach is simple to calculate, the performance is more excellent than PSNR,SSIM and better than MS_SSIM.
Key words: peak signalnoise ratio (PSNR); structural similarity (SSIM); multiscale structural similarity (MS_SSIM); image quality assessment (IQA); human visual system (HVS)
