Using Enhanced Spherical Images for Object Representation

摘要

The processes involved in vision, manipulation, and spatial reasoning depend greatly on the particular representation of three-dimensional objects used. A novel representation, based on concepts of differential geometry is explored. Special attention is given to properties of the enhanced spherical image model, reconstruction of objects from their representation, and recognition of similarity with prototypes. Difficulties associated with representing smooth and non-convex bodies are also discussed. (Author)
