An Efficient Combined Inter and Intra Prediction Scheme for Video Coding

摘要：

Inter prediction and intra prediction are utilized by video coding standard H.264/AVC to exploit the temporal and spatial redundancy respectively. To further improve coding efficiency, combined inter and intra prediction was proposed to produce more accurate prediction signal. However, these methods suffer from either high computation or limited improvement. In this paper we present an efficient inter and intra prediction scheme, which decides intra prediction mode in the combination mode pair adaptively and combines the inter- and intraprediction signal using fixed spatial-variant weighted coefficient. Experimental results show that the proposed method achieves additional coding gain of up to 0.68％ compared to H.264/AVC.
