Abstract

Inter prediction is an important component for video coding which exploits the temporal correlation between frames and significantly reduces the redundancy in video sequences. In this paper, we propose a predictive patch matching for inter prediction based on template matching prediction. Besides the surrounding reconstructed pixels which form the template in template matching prediction, our proposed patch matching is able to utilize the predicted pixels generated by the traditional motion prediction. A linear combination of the reconstructed template and the predicted pixels permits to synthesize a prediction while maintaining the local variations of the target block. Furthermore, a mode selection mechanism is introduced to adaptively select the predictive patch matching at sub-block level. Experimental results demonstrate the effectiveness of our proposed predictive patch matching. Constant coding gain can be achieved by our scheme at both low and high bit rates
