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.
