Fast Layered Bit-Plane Matching for Electronic Video Stabilization

Abstract

A fast electronic video stabilization system based on layered bit-plane matching is presented, which includes global motion detection and error motion compensation. The inter-frame translation is estimated by multi-resolution pyramid matching with different bit-planes. To accelerate the search process, the initial search point is adaptively chosen based on the high correlation of adjacent blocks and father-children blocks. Furthermore, each block is judged to verify the motion accuracy to finish the search in advance. Then, the global translation is obtained according to the statistical clustering of all local motions. Lastly, the inter-frame motions are accumulated with a damping coefficient to provide the warping motion, which is compensated to realize stabilization. Experimental results show that the system shows good performance in speed with error below 0.5pixel. And it can smooth unwanted translation of video sequences at real-time speed.
