| Abstract(in English) | We are developing an efficient lossless video coding scheme based on motion compensation and block-adaptive 3D prediction. In this scheme, multiple 3D predictors which use both the current and motion-compensated previous frames are optimized for each frame. Since the optimized predictors and their assignment must be sent as side information, the number of the predictors and their prediction order are important parameters which affect the tradeoff between the number of coding bits for the side information and that for prediction errors. This paper describes a method of setting the respective parameters automatically for each frame. From coding simulations performed for several video sequences with different sizes, it is shown that the method gives appropriate settings of the parameters and, as a result, the overall coding rates including the side information are improved by 0.017 bits/pel on average. |
