Abstract

Mesh motion estimation is a tracking technique useful in particular for low bitrate compression, object-based coding and virtual views synthesis. In this article we present a new triangular mesh tracking algorithm preserving the mesh connectivity. Our method generalizes the rigid template tracking method proposed by Jurie and Dhome [5] to the case of non-rigid objects. Thanks to a learning step that can be done off-line for a given number of nodes, the tracking step can be performed in real time.
