Image Retrieval Technology Based on Multi-Feature Fusion in MPEG-7

For MPEG-7 low efficiency problems in image retrieval by using a single feature retrieval,the paper presents a new content-based image retrieval method on main color and edge histogram feature fusion.Retrieval accuracy can be improved by retrieval target characteristics of the distribution and block-weighted.Experiments show that the method in the precision rate and recall rate is better than a single feature of the retrieval algorithms,retrieval accuracy is improved.
