A Progress Report on VISIONS: Representation and Control in the Construction of Visual Models.
Hanson,Allen R., Edward M. Riseman · Defense Technical Information Center (DTIC) · 1976
This report is an interim progress report on the evolving structure of VISIONS, a computer system for general visual perception. The goal of the system is the segmentation and interpretation of a digitized color image of natural outdoor scenes. The report outlines the multi-level data structures used for representing both a visual model of the scene and the semantic data base of stored knowledge about the world. A flexible modular strategy controls the operation of processes which embody diverse forms of knowledge, and allows both data-directed and knowledge-directed model building. A model search space is used to store a sketch of the processing history during model formation, so that limited, directed back-tracking will be facilitated.
