Abstract

We introduce a novel 3D object retrieval method that is based on not only the topological information but also the partial geometry feature of 3D object. Conventional approaches for 3D object similarity search depend only on global geometry features or topological features. We use the thickness distribution along the segment of curve-skeleton as the partial geometry feature of 3D object and define the connection of the segments of curve-skeleton as the topological feature of 3D object. In order to retrieve 3D objects, we match 3D objects by their thickness distributions along segment on the curve-skeletons. Furthermore, we use the connection information of segments to improve the accuracy of partial similarity retrieval. The experimental evaluation shows that our approach yields meaningful results in the articulated object database.
