In order to improve retrieval precision radio of the Content-based Image Retrieval(CBIR),this paper studies image retrieval method based on salient closed edge.It designs extraction algorithm of salient closed edge,and gets the salient map by human visual attention mechanism.It confirms the salient closed edge,and obtains salient edges by linking the ruptures between salient edges.It combines with the gradient histogram and angle value histogram of edge to realize image retrieval.Experimental results show that the proposed method has higher precision ratio.
