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.
