Abstract : The report describes initial progress towards the development of a computer system that can be rapidly programmed to analyze any class of pictorial scenes. It has been awkward to develop scene analysis programs using conventional programming systems because of the difficulty of formalizing pictorial descriptions in symbolic terms. Picture processing techniques are inherently ad hoc and must be deduced empirically for each application. An interactive system specifically designed for expressing and experimenting with perceptual strategies is constructed. The system allows an experimenter to describe basic perceptual concepts to a computer in terms of pictorial examples. The examples are designed graphically by encircling areas of a displayed scene with a cursor. A concept is represented internally by values of primitive feature-extraction operators that distinguish it from examples of previously defined concepts. Concepts so defined constitute a common vocabulary, shared by man and machine, that can be used symbolically in describing objects and specifying scene analysis procedures.
