SURFACE DESCRIPTION IN RANGE IMAGES - A PARALLEL APPROACH

This paper describes a parallel rule based system which obtains a stru ctural shape description of 3-D objects from range images. The system uses a hierarchical approach to obtain higher level surface descriptio n from lower level ones. Instead of a detailed mathematical analysis, qualitative reasoning by rule based deduction is used to obtain the su rface description. ne rule bases are also hierarchical. A special purp ose shared memory architecture is suggested which supports parallel ap plication of rules.
