Abstract
Methods, apparatus, and computer-readable storage media for video completion that may be applied to restore missing content, for example holes or border regions, in video sequences. A video completion technique applies a subspace constraint technique that finds and tracks feature points in the video, which are used to form a model of the camera motion and to predict locations of background scene points in frames where the background is occluded. Another frame where those points were visible is found, and that frame is warped using the predicted points. A content-preserving warp technique may be used. Image consistency constraints may be applied to modify the warp so that it fills the hole seamlessly. A compositing technique is applied to composite the warped image into the hole. This process may be repeated until the missing content is filled on all frames.
