Abstract :
A new motion compensation mode of TM_BMC is proposed by this paper to improve video coding efficiency. In TM_BMC, the inter-prediction efficiency is improved by combining the predictor of template matching and predictor of traditional block motion compensation, the coding cost for motion vector of traditional block motion compensation is reduced by utilizing motion vector derived by template matching as motion vector predictor. Experiment results on H.264 KTA platform show that average 7.07% and up to 11.26% bit-rate can be saved by locally adaptive motion compensation mode between the traditional motion compensation mode of BMC and the proposed mode of TM_BMC.
