Abstract:

A novel block-based intra-prediction scheme is proposed for efficient image (or intra-frame) coding, where we apply various 2D geometrical manipulations to reference image blocks to enrich the pool of prediction blocks for a given target block. As compared with the traditional line-based intra prediction in H.264/AVC, the new scheme offers a significant coding gain (about 0.24∓1.23dB in the PSNR value with the same bit rate) at the cost of higher complexity. Several techniques to reduce the search complexity are also discussed.
