Abstract :
In this paper we investigate how to improve the overall prediction efficiency of intra frame coding in H.264, incorporating into the rate-distortion optimization framework several new prediction algorithms that can both fix some weaknesses of the existing 16times16 standard mode and partially fill the performance gap between available 4times4 and 16times16 strategies. Results show a good gain in performance respect to plain H.264
