Abstract :
Mesh-based motion tracking is a fast-emerging model for inter-frame video compression. This paper presents a mesh-based motion-tracking model with embedded residual image that improves the quality of predicted frames by the use of residual coding. The presented method reduces the rate of inter frame update. It has been shown statistically that the presented model is able to maintain a relatively high quality in predicted video frames at a low cost.
