Video Object Motion Tracking: A Structured Versus Unstructured Mesh Topology

摘要

This paper presents a novel concept for very low bit rate video codec. It uses a new hierarchical adaptive structured mesh topology. The proposed video codec can be used in wireless video applications. It uses structures to model the dynamics of the video object where the proposed the adaptive structure splitting significantly reduces the number of bits used for mesh description. Moreover, it reduces the latency of motion estimation and compensation operations. A comprehensive performance study is presented for the proposed mesh-based motion tracking and the commonly used techniques. It shows the superior of the proposed concept compare to the current MPEG techniques.
