Automatic registration of airborne images

Liu, D., P. Gong, Q. Guo, and M. Kelly. 2006. Automatic registration of airborne images by combining area‐based methods with local transformation methods. Photogrammetric Engineering and Remote Sensing 72(9): 1049‐1059

Deformation vector plots overlaid on areas with high and low texture.Accurate registration of airborne images is challenging because complex local geometric distortions are often involved in image acquisition. We propose a solution to this registration problem in two parts: 1) an area-based method to extract sufficient numbers of well-located control points, 2) we use the extracted control points with local transformation models to register multi-temporal airborne images.
