Abstract :
Leaky motion prediction techniques have been developed as a way to trade-off between video coding efficiency and drift error resilience. In this paper, we present a statistical analysis of leaky motion prediction in the presence of channel errors. We assume the encoder has some basic knowledge of the channel such as the channel error pattern and error rate. We derive a closed-form expression of the rate distortion function and find the analytic solution for the leaky motion prediction parameter. Two examples are presented 10 demonstrate the results.
