A new particle swarm optimization method is put forward in this paper, the proposed approach improves the basic PSO in two aspects: 1) the exclusive gbest is replaced by the weighted center of the whole swarm, which is more stable and proved to be closer to the really optimum position in the searching space; 2) the particle can adjust speed adaptively according to the environment to fly slower in...
Relevance feedback (RF) proved an effect way to improve the precision and recall of 3D model retrieval. Unfortunately, through existing methods of RF, it is straightforward to find out whether a model is similar or not, but it is impossible to find out which local part is similar or not. The new partial method of RF proposed in this paper provides a good solution, in which not only the similar models...
