3D Object Retrieval using an Efficient and Compact Hybrid Shape Descriptor
(The Eurographics Association, 2008)
Abstract We present a novel 3D object retrieval method that relies upon a hybrid descriptor which is composed of 2D features based on depth buffers and 3D features based on spherical harmonics. To compensate for rotation, ...
Retrieval of 3D Articulated Objects Using a Graph-based Representation
(The Eurographics Association, 2009)
Most of the approaches which address the problem of 3D object retrieval, use global descriptors of the objects which fail to consistently compensate for the intra-class variability of articulated objects. In this paper, a ...
