Keynote Title:Bayesian Early Mode Decision Technique for View Synthesis Prediction-enhanced Multi view Video Coding

 Abstract  Abstract: View synthesis prediction (VSP) is a coding mode that predicts video blocks from synthesized frames. It is particularly useful in a multi- camera setup with large inter-camera distances. Adding a VSP-based SKIP mode to a standard Multi view Video Coding (MVC) framework improves the rate-distortion performance but increases the time complexity of the encoder. The talk will present an early mode decision technique for VSP SKIP-enhanced MVC. The method uses the correlation between the rate-distortion costs of the VSP SKIP mode in neighboring views and Bayesian decision theory to reduce the number of candidate coding modes for a given macro block.Simulation results show that the technique can save up to 36.20% of the encoding time without any significant loss in rate-distortion performance.
