An image retrieval method based on contour feature is proposed in this work.Pair-wise Geometric Histogram(PGH) captures the outer contour feature of the target shape.Distance histogram describes the interior details.Combining with two features, a twice retrieval strategy is proposed.Firstly, the query image and database images are compared with PGH.The eligible images are as candidates.Then, the secondary retrieval is carried out between the query image and candidate images.Images meeting the conditions are as the final result.Experiments show that the proposed method can resist rotation, translation transformation and scaling transformation, which has a good performance.
