An Image Automatic Registration Algorithm for InSAR Complex Images Based on Curve Fitting
基于曲线拟合的干涉合成孔径雷达(InSAR)复图像自动配准算法

Due the presence of multiplicative and speckle noise, the method of registering InSAR image is more difficult than traditional image registration methods. In this paper , an automatic InSAR image registration method is presented, based on B-spline curve fitting and matching, that can handle the registration of InSAR image efficiently. After the registration parameters are established by the least square method, a two-step method is applied to registering with sub-pixel accuracy. The experimental results demonstrate the algorithm is of robustness, efficiency and accuracy.
