Abstract

Addresses the problems of content retrieval in the construction of pictorial database management systems. Presents a generalisable architecture for the effective identification of specific pictures from a large collection and describes prototype system based on this architecture successfully implemented. The architecture consists of 3 main components: picture description; picture indexing and filing, and picture retrieval. The description of pictures is facilitated by using the main semantic concepts employed in the entity-attribute-relationship model. The chief function of the picture indexing and filing component is to convert the logical representations into a relational data format to prepare for subsequent processing initiated by picture queries
