A large picture and text archiving system, with query facilities, has been developed for a variety of applications. Variable sized images, and their corresponding captions or descriptive files, are stored in two different segments (eventually on different media). By keyword-based queries, with logical predicates, the images satisfying the search criteria are retrieved, transferred through a high speed data link, and displayed on a monitor, together with the corresponding overlaid caption. The displayed image can then be processed on a local image workstation, without loading the host. Performances are given, as well as current extensions such as a natural language front-end. Applications are in remote sensing, mapping, document files, news services, medical images, security systems, inspection. © 1986.
