Method for adapting quantization in video coding using face detection and visual eccentricity weighting

摘要

A system encodes video by detecting the location of a facial region of a frame of the video. Sensitivity information is calculated for each of a plurality of locations within the video based upon the location of the facial region. The frame is encoded in manner that provides a substantially uniform apparent quality of the plurality of locations to the viewer when the viewer is observing the facial region of the video.
