FRAME ENCODING SELECTION BASED ON FRAME SIMILARITIES AND VISUAL QUALITY AND INTERESTS
摘要
A system an method for determining to select frames from a video sequence that have high visual appeal and can be coded at high quality when frame rates of coded video drop to such low levels that perceptual sensations of moving video are lost. A metric is derived from a candidate input frame, and such metric is used to determine whether to increase or decrease a weight accorded to the candidate input frame. In an embodiment, the metric may be the auto-exposure data associated with the candidate input frame.
