Segmentation of static scenes

Classics

This survey analyzes the complexities encountered in applying these techniques to color images of natural scenes involving complex textured objects. The approaches to segmentation are divided into two broad categories, boundary formation and region formation. The tools for extraction of boundaries involve spatial differentiation, nonmaxima suppression, relaxation processes, and grouping of local edges into segments. Approaches to region formation include region growing under local spatial guidance, histograms for analysis of global feature activity, and finally an integration of the strengths of each by a spatial analysis of feature activity.
