An Adaptive Image Stabilization Technique

Previous digital image stabilization (DIS) techniques perform hand-shake estimation independently on the horizontal and vertical directions. In this paper, we propose a new DIS algorithm that adaptively compensates hand jitter in a two-dimensional framework. The proposed method also includes improved validation criteria for motion vectors. Performance evaluation of the system is conduced based on the motion diagram and the PSNR improvement when it is used in conjunction with an H.264 codec. Experimental results substantiate the superiority of the proposed system.
