Resolving view sensitivity with surface locality

摘要

If a three-dimensional (3D) object is defined under a coordinate system that depends on viewing direction, its representation changes when the view changes. It is regarded as view sensitivity in object recognition. As an approach of solving the problem, this paper introduces an object modeling method that provides view insensitive 3D representation. Surface locality is investiated to define localized surfaces so that 3D objects can be described independently of viewing directions with their boundary surfaces and topological relations. The stability of this method is analysed and tested with range images.
