CORE - A CONTENT-BASED RETRIEVAL ENGINE FOR MULTIMEDIA INFORMATION-SYSTEMS

Rapid advances in multimedia technology necessitate the development of a generic multimedia information system with a powerful retrieval eng ine for prototyping multimedia applications. We develop a content-base d retrieval engine (CORE) that makes use of novel indexing techniques for multimedia object retrieval. We formalize the concepts related to multimedia information systems such as multimedia objects and content- based retrieval. We bring out the requirements and challenges of a mul timedia information system. The architecture of CORE is described in d etail along with the associated retrieval mechanisms and indexing tech niques. Various modules developed for efficient retrieval are presente d with some APIs. The efficacy of CORE is demonstrated in the developm ent of two multimedia systems, a computer-aided facial image inference and retrieval (CAFIIR) system and a system for trademark archival and retrieval (STAR), which have been developed at the Institute of Syste ms Science (ISS). We expect that CORE will be useful for effective pro totyping of other such multimedia applications.
