Extracting and Labelling Boundary Segments in Natural Scenes.

Abstract

This paper describes a set of programs used to perform boundary-analysis in the VISIONS scene-analysis system. These programs lead the data through a sequence of transformations: preprocessing, differentiation using a very simple operator, relaxation using case-analysis, and postprocessing. The output of the system is a set of labelled line-segments for which features such as length and confidence are computed. The lines and associated features will be passed to other portions of the VISIONS system for further analysis. (Author)
