W.: An empirical investigation of the scalability of a multiple viewpoint cbir system (2004)
James C. French, Xiangyu Jin, W. N. Martin
Abstract. Our work in content-based image retrieval (CBIR) relies on content-analysis of multiple representations of an image which we term multiple viewpoints or channels. The conceptual idea is to...
