4 and MPEG-7, are of fundamental importance for future visual information retrieval systems and their integration with multimedia information. MPEG-4 provides support for composition of audiovisual information and representation of synthetic media in multimedia environments. The MPEG-7 standard is aimed at specifying a standard set of descriptors of multimedia information. MPEG-7 also addresses standardization of structures (description schemes) for the descriptors and their relationships. Descriptors and description schemes will be associated with the content of multimedia material, to allow fast and efficient searching.
