Improving Intra mode coding in H.264/AVC through block oriented transforms

Improved hybrid coding scheme for intra 4×4 residual block produced by H.264/AVC

“…We suggest to use the improved rate-distortion function as shown in (5). The scheme which results in minimum ratedistortion cost (J) will be chosen.…”

“…In order to compensate for this lack of intra prediction in the current H.264, the usual idea is to improve the current intra prediction strategy [5][6][7][8] by adding extra intra prediction modes or adding more reconstructed pixels as reference at the present stage. For example, in [6], in order to improve the coding efficiency of intra prediction in H.264, the authors proposed a bidirection intra prediction (BIP) method, this method includes two schemes.…”

Improved Intra-coding Methods for H.264/AVC

“…From the above-mentioned analysis, current-enhanced intracoding methods still have problems remained, namely, either changing the coding structures a lot (e.g., [5,6]) or having limited usage (e.g., [9,10]) or alternatively less gain (e.g., [4]). In this paper, we focus on how to improve the performance of intracoding without incurring high cost of complexity and major changes for the design structure of H.264/AVC.…”
