Abstract : An error corruption model (ECM) to describe the interframe error propagation phenomenon in a motion-compensated predictive video codec using fluid flow characteristics is proposed in this research. First, we derive a diffusion equation and discuss its solution, which captures the damping effect of error propagation. Then, we propose a tracking quadrilateral (TQ) mechanism to capture the shaping and drifting effects of error propagation. Finally, we integrate these building blocks to form an adaptive fluid-based ECM (F-ECM). The accuracy of the proposed F-ECM is verified by experimental results.
