Fallback detection in motion estimation

摘要

Techniques related to managing the use of motion estimation in video processing are discussed. Such techniques may include determining dividing two video frames each into corresponding regions, generating phase plane correlations for the corresponding regions, determining whether the video frames are motion estimation correlated based on the phase plane correlations, and providing a video frame prediction mode indicator based on the determination.

1. A computer-implemented method for managing motion estimation in video processing comprising:
dividing a first video frame of a video sequence into first regions and a second video frame of the video sequence into second regions corresponding to the first regions, wherein the first regions and the second regions comprise global regions; generating a plurality of phase plane correlations, wherein each phase plane correlation of the plurality of phase plane correlations is based on a corresponding pair of first and second regions; determining whether the first video frame and the second video frame are motion estimation correlated based at least in part on the plurality of phase plane correlations, wherein the first video frame and the second video frame are determined to be not motion estimation correlated when any of the plurality of phase plane correlations indicates a fast motion, and wherein a first fast motion for a first phase plane correlation of the plurality of phase plane correlations is determined based on a comparison of a motion vector associated with a maximal peak of the first phase plane correlation and a threshold; and providing a video frame prediction mode indicator based at least in part on the determination.
