To improve performance of electronic image stabilization system, the principle of choosing motion estimation algorithm in designing system of electronic image stabilization is put forward. Through comparing the performance of projection algorithm and block matching algorithm applied to airborne image sequences, the application of the principle is shown. The simulation results show that the chosen motion estimation algorithm based on the principle applied to electronic image stabilization system is feasible.
