SUBBAND VIDEO CODING RESEARCH

该项目涉及用于视频应用的子带编码的研究，包括高级电视、视频会议和高清晰度电视(HDTV)。已经发现，子带编码结构是结合编码效率以及视频格式之间的分辨率兼容性的一种有吸引力的方式。此外，可以在子带结构内使用基于金字塔的运动补偿策略，以进一步提高编码效率。三维子带编码提供了令人兴奋的新的可能性来直接考虑编码器模块内的局部平面运动。

This project involves research into subband coding for video applications, including advanced television, video conferencing, and high-definition television (HDTV). The subband coding structure has been found to be an attractive way of incorporating both coding efficiency as well as resolution-compatibility between video formats. Aditionally, pyramid based motion compensation strategies can be used within the subband structure to further enhance the coding efficiency. Three-dimensional subband coding offers exciting new possibilities to directly consider locally planar motions within the coder module.
