融合多特征的图像检索算法
An Image Retrieval Algorithm Based on Multi-feature Fusion
摘要
Abstract
In order to solve the problem that the single feature cannot represent an image completely,an im-age retrieval algorithm based on multi-feature fusion is proposed. First,the generalized search tree( GIST) features of the query image and all the images in the image library are extracted. The similarity of two ima-ges is measured by the Euclidean distance. The image library is retrieved by the GIST feature of the query image,and the results are arranged by sorting the similarity value. Second,the scale invariant feature trans-form( SIFT) features of the query image are extracted as well as the k sub-images which are at the front of the returned results. Then,the feature matching is performed by best bin first( BBF) algorithm. Finally, the retrieval results are returned by sorting the number of matching points. The experiment is carried out on the improved Corel1000 dataset. Compared with traditional single feature image retrieval algorithms, the proposed algorithm not only improves the retrieval accuracy but also achieves better retrieval efficiency.关键词
