| Abstract: | This communication addresses the problem of automatic registration of raw images issued from an airborne multispectral imaging scanner with the aid of reference ortho-images available by classical aerial photography. We develop the proposed model, which accounts for a scan line shift process, in order to compensate for the roll motion of the aircraft, in addition to a RST deformation. The estimation of the model parameters is performed by using a PDE-based approach for the maximization of the mutual information between the source and the target image, starting from an initial estimate of the scan line process. We assess the robustness of this method and show an example of application to aerial image data. | ||
