Color Image Retrieval Based on Tolerance Granules
Xiaoyan Li · Journal of Guangxi Normal University · 2011
The extraction and representation of image feature is the basis of image retrieval technique and color image edge is the important information of human visual perception.Firstly,the color edge of raw image is extracted by using canny detection operator.Secondly,the color of image edge is quantified dynamically through the merger calculation of tolerant granule.Finally,the similarity between images is calculated with the information granules.Experimental results show that the proposed algorithm has better precision rate and recall rate than the traditional one.
