Performance Comparison of Emerging Dirac Video Codec with H.264/AV

摘要

Video compression has never been more essential than it is today. With the rapid growth of the Internet and the introduction of high-definition media, the need for continual improvements on video coding techniques is vital to keep up with emerging technologies. Dirac video codec is probably new to the video coding researchers, but it has long been a focal point to the open source hobbyist. A recent progress in its development has made Dirac a video compression tool worth considering within video coding research. This paper analyses the performance of Dirac in comparison to the more established H.264 video codec.
