MOTION ESTIMATION SYSTEM AND METHOD FOR A VIDEO ENCODER |
摘要 |
<p>A motion estimation system for a video coder is disclosed. The system comprises an input for a video image (6) to be coded. It also comprises a series of motion estimators (2, 3) of varying complexity, for estimating a motion vector field between the received image (6) and a reference image (5). The subsequent motion estimator in the series is selected by a control means (4) if a prediction error associated with the motion vector field estimated by the currently selected motion estimator exceeds a predetermined threshold.</p> |
