Abstract :
A novel intra coding scheme is proposed to improve coding performance in intra pictures of H.264/AVC. The proposed method generates two sub-images, which are defined as a sampled image and a prediction error image in this paper, from an original image, and then encodes them separately. Especially, in an intra prediction process of encoding, the sampled image employs the original intra prediction modes, while the prediction error image uses newly defined four intra prediction modes. Experimental results demonstrate that the proposed method achieves significantly higher intra coding performance and reduces encoding complexity with the smaller number of a rate-distortion (RD) cost calculation process, as compared with the original intra coding method of H.264/AVC.
