3D Objects Feature Extraction and Its Applications: A Survey

Haisheng Li, Xuan Liu, Qiang Cai, Junping Du

Abstract: As large public repositories of 3D objects continue to grow, more and more feature extraction technologies for 3D objects spring up. On the basis of classical algorithm, new factors have been added to these emerging technologies. Feature extraction technologies, which are based on shape structure and geometry information, include semantics, kinematics and cognition, etc. While the technologies have been developing, using features to solve problem is more important than just extracting features from 3D objects. In this paper, we summarize several feature extraction technologies from different aspects. Then we aim at the applications of 3D object feature, not just the general 3D models retrieval, mainly about some specific applications and target on 3D CAD objects, non-rigid 3D objects and deformable objects.
