A new predictive block-matching motion estimation scheme is proposed in this paper for efficient video codec design. The proposed Scheme is based on the “inertia” effect of natural video scenes and takes advantage of the motion vectors obtained in the previous frames. Not only motion searching time and overhead are significantly reduced, the proposed scheme also provides realistic motion tendency, which is very useful for frame skipping/interpolation techniques. These advantages are also demonstrated by some experimental results obtained on Abekas video system.
