Querying Relational MPEG-7 Image Database with MPEG Query Format

The growth of multimedia is increasing the need for standards to access and search distributed repositories. Recently, the Moving Picture Experts Group (MPEG) has developed the MPEG Query Format (MPQF) to make multimedia access and search easier and interoperable across search engines and repositories. Since MPQF is not supported by any database products including native XML databases and relational databases, a translation of MPQF to the multimedia database query language is required. This paper presents a system for querying relational MPEG-7 image database with MPQF. A translation of selected query types from MPQF to SQL is proposed based on an especially designed relational schema that preserves typed data of the image descriptions.
