Automatic Data Processing Techniques for Graphic-Data Display, Generation and Analysis.

Abstract

This is an Interim Technical Report describing research carried out under Grant AFOSR 76-2937 during the 12-month period 1 September 1976 - 31 August 1977. The overall objective of the research program is to make significant improvements in the state of the art relating to the extraction, representation and computer interpretation of line drawing data. Specific tasks during the reporting year were concerned with (1) the reconstruction of solid-object descriptions from multiple photographic projections, (2) the development of programs for the removal of 'hidden lines' from the projection of both planar-faced and quadric-surface objects, (3) the design of a generalized chain coding scheme for the compact and precise description of map data, (4) the development of a line-drawing processing language, (5) an investigation into some new approaches to scale- and orientation-independent shape classification.
