AUTOMATIC VIDEO QUALITY ENHANCEMENT WITH TEMPORAL SMOOTHING AND USER OVERRIDE

摘要

Technologies for a single-pass process for enhancing video quality with temporal smoothing. The process may include providing for user overrides of automatically enhanced video/frame characteristics and providing substantially immediate previews of enhanced video frames to a user. The process may also include detecting a degree of shakiness in a portion of the video, and performing or recommending stabilization based on the detected shakiness.

主权项

1. A method performed on a computing device, the method for enhancing quality of a series of frames, the method comprising:
decoding, by the computing device, a frame of the series of frames; deriving, by the computing device from the decoded frame, data for a characteristic of the frame; generating, by the computing device, correction parameters based on an integral of a variation of the derived data; and smoothing, by the computing device, the characteristic, where the smoothing comprises adjusting the generated correction parameters based on correction parameters of other decoded frames from the stream of frames, where the other decoded frames, if any, are located prior to the decoded frame in the series.
