A 2D autoregressive method for deformation evaluation in registration of remote sensing data

A registration method is developed based on an A* algorithm in conjunction with a 2D autoregressive model used for image representation. The A* algorithm serves for obtaining the initial pixels which used further for determining the innovation process. Prior to this step the 2D autoregressive parameters are calculated using an initial set of pixels from the original image. The error measured between the innovation and the primitive pixels of the subject image is then considered as the exact function for the A* algorithm. The process is recursively applied until the whole set of primitives is registered. An example illustrates the approach
