| 摘 要： | 研究了一种基于回归分析的图像全局运动估计与补偿技术,首先利用光流场法估计局部图像背景点的速度场,然后利用鲁棒的叠代排除法估计图像传感器的全局运动模型参数,再利用估计出来的全局运动参数对图像进行双线性内插运动补偿。这种技术具有计算量少,实现简单,性能可靠等优点。

| Abstract: | Global motion parameters are estimated using regression technique,which first estimats the local motion and then uses the local information to find the global motion that minimize the least square error.Then the global motion was compensated using these parameters.Refinements are carried out during the estimation inner process based on iterative elimination of singular values which introduce the bias to the estimated parameters.The proposed technique is not only computationally simple,but also has high perfomance.Theoretical analysis of the technique's performance and experimental results are also given in this paper. |
