摘要
采用加权处理的方法,讨论了一种基于人眼视觉特性和结构相似度图像质量评价方法,将图像划分并计算出每个分块的结构相似度,根据每个分块的亮度,纹理细节和分块空间位置对人眼视觉的影响,确定每个分块的权值,计算出加权平均的结构相似度作为图像质量的评价指标.经实验验证,评价结果与主观评价结果一致.
An approach was discussed through analyzing the influence of three factors： brightness, texture details and dimensional position, which based on the characteristic of human visual system and structural similarity of images. On the first, the image was divided using equal sized sliding windows, then the structural similarity with the factors influence were calculated, and the weighted value also be determined. The experiment results indicated that the approach has a good correlation with the objective criteria.
