CASCADED CAMERA MOTION ESTIMATION, ROLLING SHUTTER DETECTION, AND CAMERA SHAKE DETECTION FOR VIDEO STABILIZATION

摘要

An easy-to-use online video stabilization system and computer implemented video stabilization methods are described. Videos are stabilized after capture, so stabilization works for all types of video scenes, including both legacy video and recently captured video. In one implementation, the video stabilization system is completely automatic, so it does not require any input or parameter setting by a user other than the video itself. The video stabilization system uses a cascaded motion model to select corrections applied to different frames of the video. In various implementations, the video stabilization system can detect and correct both high frequency jitter artifacts, low frequency shake artifacts, rolling shutter artifacts, large foreground motions, poor lighting, scene cuts and long and short videos.
