摘要：
Global motion estimation is a powerful tool used in computer vision and video processing. In this paper, we propose an efficient approach of estimating general global motion parameters from coarsely sampled motion vector fields. The approach is based on Newton-Raphson method with outlier rejection. Experimental results show the effectiveness of the method in terms of robustness and accuracy.
