| Abstract | In this paper, we propose a novel feature, called object flex-ibility, at a point of a 3D object to describe how the neigh-borhood of this point is massively connected to the object. We show that this feature is stable to the deformation of ob-jects ’ articulations, in addition to commonly concerned lin-ear transforms, i.e., translation, scale, and rotation. A shape descriptor is obtained based on this feature using the bag-of-words model. As an application, the descriptor is used to perform 3D object retrieval. Extensive experiments demon-strate its superiority over a variety of existing 3D shape de-scriptors in the retrieval of articulated objects, as well as its enhancement of other shape descriptors to retrieve generic 3D objects. |
