In this paper, a new 2D cepstral descriptor will be proposed for 3D model retrieval. In the proposed approach, the overlapping subband decomposition will be employed to divide each 2D spectrum into a number of overlapped subbands for further 2D cepstral descriptor extraction. Experiments conducted on the Princeton Shape Benchmark (PSB) database have shown that the proposed 2D cepstral descriptor yields...
The demand of 3D object retrieval became urgent according to the widely use of 3D printer. In this paper, a 3D object retrieval method is proposed using multiple features and manifold ranking. Five descriptors are concatenated to be a new feature vector of length 792 for 3D object retrieval. They are angular radial transform-based elevation descriptor(ART-ED), principal plane descriptor(PPD), 3D-angular...
In this paper, we will propose a 3D model retrieval approach using 2D cepstral features. First, six projection planes representing the elevation (depth) value are generated. Then, 2D cepstral features are extracted from each projection plane for searching similar 3D models. Experiments conducted on the Princeton Shape Benchmark (PSB) database have shown that the proposed 2D cepstral features outperforms...
In this paper, the combination of different projected shape features is proposed for 3D model retrieval. The projection features include the elevation value (depth), the radial distance, and the angle of a surface mesh. For each of the characteristic values (elevation value, radial distance, and angle value), six projection planes represented as gray-level images will be generated. The MPEG-7 angular...
In recent years, the demand for a content-based 3D model retrieval system becomes an important issue. In this paper, the cylindrical projection descriptor (CPD) will be proposed for 3D model retrieval. To derive better retrieval results, the CPD will be combined with the radial distance descriptor (RDD). The experiments are conducted on the Princeton Shape Benchmark (PSB) database. Experiment results...
In recent years, advanced techniques on digitization and visualization of 3D models have made 3D models as plentiful as images and video. The rapid generation of 3D models has made the development of efficient 3D model retrieval systems become urgently. In this paper, we will propose a feature integration approach in which a weighted distance method is developed to combine the distance evaluated by...
