FAST MOTION ESTIMATING METHOD USING ADAPTIVE SCAN BASED ON IMAGE COMPLEXITY

摘要

The invention matching between that, the present invention is to implement a motion high speed prediction method in the video encoder, the search of the reference block and a previous frame of the current frame changnae each candidate block according to the motion high-speed prediction method in the video encoder to compress video data, applying the method, the adaptive matching scanned (adaptive matching scan) to adopt a search direction of the direction helix on the search changnae and determines the matching scanning direction on the basis of the complexity of the reference blocks to scan, and at the same time, during the determined matching scanned If it is determined as a non-candidate block removing part error that stops the matching scanned for that candidate block: by applying (PDE partial Distortion Elimination), can significantly reduce the amount of calculation in the entire area search (full search), yiettara between frames to be able to perform motion estimation at high speed around the search area for motion estimation Algorithms can be implemented.
