| Abstract: | The technology of video coding has dramatically promoted a wider application of digital media, while transform coding is one of the key technologies in video compression, which determines the coding efficiency and increasingly becomes a research focus especially in current popular coding 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 hexagonal transform method as well as its integer approximation applied in video coding. Experiments show that it achieves a higher performance. |
