Abstract

Motion estimation and compensation are main stages in hybrid video coding standards. Due to structural simplicity the block-matching motion estimation is the most used method in digital video technology. In recent years the mesh-based motion estimation is considered by the researchers because of its more complex motion models and lack of blocking artifacts. However, mesh-based motion estimation suffers from error propagation and weak performance in noisy and brightness varying conditions. In this paper motion adaptive interpolation functions are proposed for the mesh-based motion estimation to overcome these problems. The simulation results show the better robustness of the proposed scheme against noise and brightness variations, not only regarding to mesh-based but also block-matching motion estimation techniques.
