  • Based on cross sub-image block, a novel algorithm of digital image stabilization is presented, which makes use of the similar features existed between adjacent images. First, the representative points which represent global features are acquired through crossing sub-image blocks. Then, on the basis of motion model, energy function is structured, through which, the representative points between adjacent images are matched and global motion parameters can be estimated. Finally, the image stabilization process is realized via motion compensation with cumulated global motion parameters. The combination of representative points and motion model could produce good performance when the image fluctuation contains both translational and rotational motions. And results of strong noise experiments show the robust of the algorithm.
