SPATIALLY ADAPTIVE VIDEO CODING

摘要

A video signal comprises a sequence of source frames to be encoded. A pre-processing stage determines a region of interest for a plurality of the source frames, and spatially adapts each of the plurality of the source frames to produce a respective warped frame. In the respective warped frame, the region of interest comprises a higher spatial proportion of the warped frame than in the source frame. The pre-processing stage supplies the warped frames to an encoder to be encoded into an encoded version of the video signal.
