Registration of Remote Sensing Images Based on the Relevance Vector Machine

Remote sensing has become a technique of indispensable importance for us to acquire the information on the ground. In the process of imaging, geometric distortion occurs due to several factors, which causes many difficulties when using those remote images for change detection, information fusion, resolution enhancement and so on. So the image registration is necessary. Aiming at the distortion type for the selection of geometric transformation model in the registration process, a relevance vector machine (RVM) based geometric transformation model is given, which will solve the problem of nonlinear geometric distortion efficiently as well as avoiding the shortcomings in the traditional model. Experiments have been realized this method.
