摘要 图像质量评价对于各种视频图像应用具有重要的意义。结构相似度准则SSIM在模糊图像及噪声污染的图像判定方面,存在偏差。该文提出了基于双尺度边缘结构特征的图像质量评价算法——MDESSIM,充分考虑了边缘信息在结构信息中的重要性,通过增加边缘结构的失真度量来综合评价图像质量。实验结果表明了MDESSIM算法的有效性。  The quality assessment of images is meaningful for most video and images applications.The structure similarity index(SSIM) shows some defects when evaluating the quality of blur images and noise images,the results don’t match the HVS system well.This paper proposes a new image quality assessment algorithm based on dual-scale edge structure similarity(MDESSIM).The edge information is appreciated sufficiently during the structure information in this algorithm.The distortion metric of edge structure is included in the assessment of the image quality.Experimental results demonstrate the MDESSIM algorithm is effective.
