Color is one of the most important features for content-based image retrieval,which is easy to perceive.Color histogram can reflect basic color and statistical distribution perfectly.However it can only measure the distribution of color in the overall differences without measuring spatial location information..In this paper,author proposes an improved method called dominant color matrix based block which can enhance the main color of images and dim secondary color.It can capture the color spatial location relationship in order to enhance the spatial distribution of color histogram.Though resolutions of different pretreatment,it can reduce the computational complexity,improve the operating efficiency and save storage space.
