英文摘要 | In order to improve the coding efficiency for intra-prediction in H.264, we propose a novel intra-prediction mode of the H.264 standard for aerial area CCD camera in this paper. The idea of the proposed intra-prediction mode is that each pixel within a block is predicted by a weighted sum of its neighbors, according to an N-th order linear predictor. The weights are obtained from reconstructed data in the neighbor blocks which are selected by l1-norm-based approach. Therefore, the decoder doesn't need to convey the weights to the decoder, which can be very time consuming. Finally, the proposed intra-prediction mode is implemented in H.264 reference software JM17.6. The experimental results show that the proposed intra prediction algorithm has better rate-distortion (RD) performance. Compared with the intra prediction for regular H.264 standard, the proposed method could improve the average peak signal to-noise ratio (PSNR) by 0.57-0.17 dB for images, 0.05-0.14 dB for CIF-resolution sequences, 0.01-0.05 dB for 720p50-resolution sequences, while the bit-reductions are 9.71-3.94%, 1.23%-1.52%, 0.25%-0.47%, respectively. It is suitable for the application in aerial area CCD camera. |
