A novel 8×8 transform method applied in video coding

Transform Coding has been playing an important role in video coding and increasingly becomes a research focus especially in the current popular standards such as H.264/AVC, AVS and HEVC. It is important to select an excellent transform method as transform module has a direct impact on the efficiency of video codec. This paper proposes a new 8×8 transform method as well as its integer approximation applied in video coding. Experiments show that it achieves a higher performance.
