(An) efficient object representation for CAD-based 3-D object recognition

Abstract

In this thesis, a solid modeler by which one can automatically and efficiently build the 3-D object models is proposed. The proposed method provides a fast and compact object representation by incorporating view-dependent features and the object-centered representation. To test the efficacy of the proposed object representation scheme for recognition, we have implemented a matching process based on the constrained search paradigm Experimental results show that the proposed method can reduce the time and storage space during the recognition process.
