Restoration Technique of Video Motion Image Estimation Based on Wavelet

Video compression technology is the research field of video compression coding attention. It mainly includes the elimination of temporal redundancy and spatial redundancy elimination algorithm, this paper mainly focuses on the study of motion estimation and compensation algorithm to eliminate the temporal redundancy. The starting point of this article is how to improve the precision and the subjective quality of the reconstructed image motion estimation and compensation, to reduce the computation complexity of motion estimation algorithms, to improve the efficiency of motion estimation. This paper makes some studies on the redundant wavelet domain block matching motion estimation and compensation, then the video image for non translational motion, the DT triangular mesh motion estimation and compensation in the redundant wavelet domain to do related research. Experimental verification, the algorithm can effectively extract the feature points of video image stabilization and improve the matching, motion estimation and compensation accuracy and efficiency, and the subjective quality of reconstructed image is good, especially for non translational motion video sequence motion estimation effect..
