Development of an Expert System for Interpretation of Oceanographic Images
Abstract
Current work is directed toward developing and implementing a prototype expert system that 'knows' about mesoscale ocean features in the Gulf Stream. The domain of the prototype system is a sequence of registered satellite infrared images. The events represented in the knowledge base are landmass boundaries, warm-core eddies, cold-core eddies, boundaries of the Gulf Stream, and areas on the Gulf Stream boundaries in which locally rapid changes are occurring. The logical/mathematical representation for each type of event includes a set of attributes that range from single numerical values to functions that describe shape. Later versions will attempt to use inference rules to fill in information concerning areas obscured by clouds by processing information about events from all images in a sequence. A major portion of the report consists of a tabulation of knowledge-base information about warm-core rings, cold-core rings, and the Gulf Stream. The knowledge base includes information on the formation, expected movement, evolution and decay of rings, other ring characteristics and special cases, and general information about the Gulf Stream.
