Xuefan Zhang · Jisuanji fangzhen · 2006
To improve the efficiency of 3D model retrieval, an efficient retrieval of 3D models based on block was proposed. The axis skeleton, the information of geometry and topology of skeleton point were got after preprocessing of model. The skeleton was segmented into a set of blocks. The weight was defined for each block of the skeleton. Finally, by calculating the similarity between blocks, the similarity of 3D models was achieved. The experimental results show that this algorithm can achieve better retrieving efficiency than other algorithms.
