Content based image retrieval using topological models

This paper presents a step in a long process of analyzing, structuring, and retrieving multimedia databases. Indeed, we propose to bring an improvement to an existing content based image retrieval approach. We propose an effective method for locally updating neighborhood graphs which constitute our multimedia index. This method is based on an intelligent way for locating points in a multidimensional space. Promising results are obtained after experimentations on various databases. Future issues of the proposed approach are very relevant
