SHREC'08 Entry: Hybrid IIT-NCSR-Demokritos


In this paper, we present an overview of the 3D object retrieval method that we employed in our participation to the Generic Models track of SHREC 2008 organized by the AIM@SHAPE network of excellence. The proposed methodology is detailed in [2]. Our method is based on a hybrid scheme where 2D features as well as 3D features are extracted from a 3D model which has been previously normalized for rotation using two alternative alignment techniques. The alignment methods that are used are CPCA and NPCA. The 2D features are Fourier coefficients extracted from a set of depth buffers and the 3D features are spherical harmonic coeffi- cients extracted from a spherical function-based representation of a 3D model.
