ABSTRACT

Image registration and image fusion processes are important operations in remote sensing applications, robotics, target tracking/identification and medical imaging. The aim of registration is to geometrically align the two images—the source and the target images. Image registration is usually followed by generation of large panoramic images for viewing and analysis. The aim of satellite image registration is to align the satellite images obtained at different points of time so that changes such as movement of clouds, growth of vegetation and so on can be detected. The increased volume of satellite images has reinforced the need for automatic image registration methods. Image fusion of multisource images will have effects of denoising, resolution improvement, definition improvement and compensation for loss or failure from one sensor. The most important issue concerning image fusion is to determine how to combine the different sensor images.
