Image Retrieval Based on Sub-block Dominant Color Matching
Liu Pi-e · Jisuanji gongcheng · 2010
In order to solve the problem of lacking the spatial knowledge of color histogram,an approach of image retrieval based on dominant color of partition is presented.It designs overlapped sub-blocks to get the color accumulative histogram in each block.Meanwhile,the reduced quadratic form distance method is applied to decrease arithmetic complexity.The similarity is calculated based on the accumulative histogram of each region.Experimental results show the algorithm can greatly reduce the dimension of color feature,and keep high retrieval precision simultaneity.
