A System for Query by Example in Image Data Base Angelo Chianese, Antonio Picariello, and Lucio Sansone   View Paper (PDF)   Return to Papers Abstract Processing queries for databases containing multimedia information is a hard question. In this paper we describe a knowledge base approach to effectively resolve query by examples in image database. We present a prototype system that is at the moment under developing in our Labs. We consider wavelet descriptors for modeling color, shape and texture features, and we propose a knowledge base for assisting the user in the retrieval process. Results on a collection of about 1000 images are reported to provide a validation of the proposed strategy. DiSC'02 © 2003 Association for Computing Machinery
