Abstract

We present an automatic topology change detection and mesh editing interface for Time-Varying Meshes (TVMs). A TVM is a sequence of 3D mesh models of real-world objects generated from multiple-view images. Changes in their topology are detected by extracting skeletons from them and tracking the motion of the skeletons. An interactive tool for mesh editing has also been developed. As a result, the time consistency of the mesh topology can be maintained thus enabling us to apply several mesh processing algorithms to TVMs. The validity of our system was confirmed by applying an edited TVM sequence to motion tracking. Experimental results demonstrate that the tracking accuracy was improved by 859.4 mm in the best case.
