IMAGE RETRIEVAL BASED ON BINARY SIGNATURE AND Sk GRAPH

In this paper, we introduce an optimum approach for querying similar images on large digital-image databases. Our work is based on RBIR (region-based image retrieval) method which uses multiple regions as the key to retrieve images. This method significantly improves the accuracy of queries. However, this also increases the cost of computing. To reduce this expensive computational cost, we implement a binary signature encoder which maps an image to its identification in binary. In order to speed up the lookup, binary signatures of images are classified by the help of S-kGraph. Finally, our work is evaluated on COREL’s images.
