Abstract :
Images with rapid motion are more or less degraded at low bit rate transmission. Hence a motion compensation technique is implemented to improve the coding efficiency. Performance in terms of bit rate is compared between motion compensated and nonmotion-compensated multimode video coding. Multimode video coding optimizes the tradeoff between the conflicting objectives of high compression ratio and error resilience.
