CONTENT ADAPTIVE DOMINANT MOTION COMPENSATED PREDICTION FOR NEXT GENERATION VIDEO CODING

摘要

A computer-implemented method for video coding comprising obtaining frames of pixel data and having a current frame and a decoded reference frame to use as a motion compensation reference frame for the current frame, forming a warped global compensated reference frame by displacing at least one portion of the decoded reference frame by using global motion trajectories, determining a motion vector indicating the motion of the at least one portion and motion from a position based on the warped global compensated reference frame to a position at the current frame, and forming a prediction portion based, at least in part, on the motion vectors and corresponding to a portion on the current frame.
