Bayesian Early Mode Decision Technique for View Synthesis Prediction-enhanced Multiview Video Coding

View synthesis prediction (VSP) is a coding mode that predicts video blocks from synthesised frames. It is particularly useful in a multi-camera setup with large inter-camera distances. Adding a VSP-based SKIP mode to a standard Multiview Video Coding (MVC) framework improves the ratedistortion (RD) performance but increases the time complexity of the encoder. This paper proposes an early mode decision technique for VSP SKIP-enhanced MVC. Our method uses the correlation between the RD costs of the VSP SKIP mode in neighbouring views and Bayesian decision theory to reduce the number of candidate coding modes for a given macroblock. Simulation results showed that our technique can save up to 36.20 % of the encoding time without any significant loss in RD performance.
