SCENE ANALYSIS USING THE CONCEPT OF MODEL,
Adolfo Guzmán Arenas · Defense Technical Information Center (DTIC) · 1967
A symbolic notation (FDL-1) for the description of pictures composed of rectilinear segments is developed. Visual objects, aggregates of objects (scenes) and generalized classes of objects (models) may be expressed in this notation. A program is described which, given a scene S and a model of an object O, finds all instances of O in S. (O and S are expressed in FDL-1). The program, written in the language CONVERT, can identify overlapping objects when they are transparent. Examples are given.
