中文摘要：

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。

英文摘要：

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 decompo- sition and synthesis of image space vector. This method is based on the demand of image background luminance contrast similar- ity parameter and independence component. It gives corresponding design examples. Experimental results indicate image back- ground 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.
