Abstract: Due to the disadvantage of two components not analyzing the component of background luminance independently, this paper proposes a test image design method which is similar to image spatial structure based on the principle of the decomposition and synthesis of image space vector. This method is based on the demand of image background luminance contrast similarity parameter and independence component. It gives corresponding design examples. Experimental results indicate image background luminance, contrast similarity parameter and independence component are more consistence with human visual feeling, and help for the establishment of standard test signal which structure is similar.

摘要： 为了实现一种与人眼的主观视觉感受相吻合的信号设计方法，针对原有两个分量存在着没有对背景亮度分量独立分析的弱点，依据图像背景亮度、对比度相似和无关分量结构化参数的要求，基于空间向量分解和合成原理，采用了空间向量均值和范数等参量方法，提出了一种与三个误差分量的图像信号设计方法，以及对应的设计实例。实验结果表明图像背景亮度、对比度相似和无关分量与视觉感受更加吻合，有利于结构相似性的标准测试信号的建立，以及图像结构化质量评价实验的考察。
