Title: A Feature-based Method for Automatic SAR Image Registration
Abstract: Because of the presence of speckle in SAR image,the automatic registration methods of optical remote sensing image aren't applicable for SAR image directly.Feature-based method is effective for SAR image registration.The difficulty is how to get suitable features.For this,a feature-based method for automatic SAR image registration is proposed.Firstly,SAR image segmentation is done to get suitable regions,then the invariance is used to find the matching regions,and at last,the expanded controids are used.The registration results of real SAR images prove the validity and adaptability of the method.
