Algorithms for video compression

点击翻译按钮获取中文摘要

The objective of this research program is to advance compression technology by 1) investigating fundamentally different approaches to frame prediction, and by 2) investigating means to choose encoding parameters to increase visual quality. The first objective will be achieved by identifying in each video frame scene features that can be found in other frames despite differences in viewpoint, scale or illumination. By matching these features, we will then establish a correspondance between frames that will improve compression ratios. The second objective of this proposal will be achieved by integrating, into a video encoder, means to objectively evaluate the visual quality of video, and adjust encoder parameters to maximise the visual quality. Both objectives will require computationally complex algorithms. However, for offline compression, and taking into account the continuing increase in processor computational power, this will not be an impediement to the advancement of compression technology.
