Content-based search on an MHEG-5 standard-based multimedia database

Some research effort has been made to create environments for multimedia application development. It is desirable to be able to search the information based on the semantic content, rather than only on the raw data available. The authors discuss the approach that has been adopted to carry out content-based search in the multimedia database being investigated by the SMmD project. The database has been extended aimed at giving support for the retrieval of bitmap, video and text objects through some metadata containing semantic information about the objects. The characteristics of the MHEG-5 standard, which were adopted as a reference in that project, are presented
