  • A new intra coding method based on one dimensional line prediction with different transform is presented. The H.264/AVC design includes a multidirectional spatial prediction method to reduce spatial redundancy by using neighboring samples as a predictor for all the samples in a block of data to be encoded. In the proposed intra coding method, the spatial prediction is performed line-based in horizontal or vertical direction instead of in the block-based manner used in the current H.264/AVC standard, while the block structure is either retained or one dimensional based for the residual difference transform and entropy coding process. Experimental results on CIF (352 × 288) and 720P (1280 × 720) sequences show that the new line based intra coding framework reduces the bit rate by approximately 7% and up to 12% at the same PSNR in comparison with H.264/AVC baseline profile.
