Aiming at the image retrieval based on color feature,a new image retrieval algorithm based on HSV non-uniform quantization color segment histogram was presented.The basic idea of segment histogram was to divide image space into fixed blocks according to a certain strategy,and then the color histogram of each block was calculated as the color feature of the corresponding block.Users assigned a weight to each block according to the importance of the space information that the block contains,and assigned zero to the unimportant of the block.This algorithm made use of HSV non-uniform quantization and the block of image.It improved the traditional histogram for its lack of space information.Compared with traditional histogram method,the results indicate that the proposed algorithm based on HSV non-uniform quantization color segment histogram has better retrieval precision.
