The study of electronic image stabilization algorithm has an important effect in electronic image stabilization technology. This thesis introduces the basic concept and principle of electronic image stabilization. After studying several algorithms in common use ,it presents the basic structure and principle of the vehicle-borne electronic image stabilization experiment. The algorithm based on block-matchning and algorithm based on line-feature are adopted to estimate the image motion. The contrail-average algorithm is adopted to compensate the image sequences. And in the end ,the thesis presents several evaluation criterions and some tentative of the electronic image stabilization system.
