Part based Structural Description Extracting and Modeling

description of 3D objects, which combines the geometric features of individual parts with topological connections among them. Superquadric-based geons are employed to be the primitive part representation models, which are compact and powerful in shape distinction. The structural description computing framework and the modeling system are developed, experiments are carried out and some results are demonstrated. The 3D model database is built on the modeling system, which lays a good foundation for further study on 3D object analysis and recognition.
