Abstract

The fundamental problem of modelling data effectively in the context of still pictures is addressed, which marks a significant departure from the conventional means of implementing pictorial databases. In using the entity-attribute-relationship model, the main semantic concepts of entity, attribute and relationship can be represented in a simple manner which correspond very closely to the noun, adjective and verb which are the essential components of a simple desscription of a picture. Such a system has the advantage over traditional ways of representing the data in an automated system in that it allows, inter alia, the concept of relationships between two (or more) objects to be successfully represented in the database. Our basic starting point is man-machine cooperation in which the pattern processing capability of the human eye is fully exploited. As a result, it should provide a much better degree of flexibility in the identification of complex patterns. Evaluation experiments carried out on a prototype system based on this approach are able to yield precision and recall performances of over 62% and 88% respectively
