چکیده مقاله:

In this paper, we provide an effective new 3D models” retrieval system based on Poisson equation. Usually, 3D models have considered in two major kinds: directly in 3D space andindirectly by a set of 2D views that extracted from that model. Compared with the obtained results of different kind of thesekinds of methods, we try to design our 3D models” retrieval system on special 2D views that select by using Kmeans clusteringmethod that uses a set of geometric features of each silhouette toresult the most discriminating views. This will be great helpful to improve any 3D model retrieval system performance. Afterfinding the best views of each 3D model, we will use the Poisson equation to define 2D views” shape signature that used in aretrieval system in histogram form. We use the 3D shapes of McGill database to verify the performance of our proposed 3Dmodels” retrieval. The simulation results show that proposedmethod is better performance rather than some existing 2D view and histogram based shape descriptors in retrieving correctness
