概要

• 論文の詳細を見る

• This paper presents an adaptive transform coefficient scan method that effectively improves infra coding efficiency of H.264. Instead of applying one zig-zag scan to all transform blocks, the proposed method applies a field scan to a horizontally predicted block, a horizontal scan to a vertically predicted block, and a zig-zag scan to blocks predicted in other prediction modes. Experiments based on JM9.6 were performed using only infra coding. Results of the experiments show that the proposed method yields an average PSNR enhancement of 0.16dB and a maximum PSNR enhancement of 0.31dB over the current H.264 using zig-zag scan.
