针对现有评价方法不适合于多扭曲失真图像这一问题
本文展开了对多扭曲失真图像评价方法的研究。在分析图像的边缘信息和奇异值向量对视觉特征的表征能力的基础上
提出一种基于边缘信息奇异值分解的图像质量评价算法。首先
利用Sobel算子提取参考图像及失真图像视觉敏感的边缘信息
再对两图像的边缘信息进行奇异值分解
利用奇异值向量之间的夹角来描述失真图像的畸变程度。最后
采用LIVE数据库中的450张多扭曲的失真图像验证该文算法
并与MSE、PSNR、SSIM、CSSIM等算法进行了对比。实验结果表明
该文算法对多扭曲失真图像的质量评价具有更高的稳定性
主客观评价的一致性较传统评价方法更好。通过对比时间效率
该方法基本上满足实际需求
具有更高的适用性。
Due to the problem that the existing method of objective quality assessment algorithm is not suitable for multi-distorted images
the quality assessment method for multi-distorted images was studied in this paper.On the basis of analyzing capability that the singular vector and edge information representing visual feature
an algorithm of image quality assessment based on the singular value decomposition of edge information was put forward.Firstly
the edge information of the reference image and distorted image which is sensitive to visual information was extracted by using the Sobel operator.Secondly
the singular value of the edge information of two image was decomposed
then the angle between the singular value was calculated to describe the quality of the distorted image.Finally
the algorithm applied in this paper are verified by more than 450 distorted images in LIVE Multiply Distorted Image Quality Database
and the algorithm was compared with the MSE
PSNR
SSIM
CSSIM method.Experimental results show that the algorithm is more consistent with human subject scores and has greater stability for multi-distorted image than traditional methods.Through comparison with the time efficiency
the proposed algorithm can basically meet the practical demand
and the algorithm is more usability.
