The paper presents a sketch-based image retrieval algorithm. One of the main challenges in sketch-based image retrieval (SBIR) is to measure the similarity between a sketch and an image. To tackle this problem, we propose an SBIR-based approach by salient contour reinforcement. In our approach, we divide the image contour into two types. The first is the global contour map. The second, called the salient contour map, is helpful to find out the object in images similar to the query. In addition, based on the two contour maps, we propose a new descriptor, namely an angular radial orientation partitioning (AROP) feature. It fully utilizes the edge pixels' orientation information in contour maps to identify the spatial relationships. Our AROP feature based on the two candidate contour maps is both efficient and effective to discover false matches of local features between sketches and images, and can greatly improve the retrieval performance. The application of the retrieval system based on this algorithm is established. The experiments on the image dataset with 0.3 million images show the effectiveness of the proposed method and comparisons with other algorithms are also given. Compared to baseline performance, the proposed method achieves 10% higher precision in top 5.
