Abstract
A method and system for creating a high spatial resolution image from a multidimensional imagery is disclosed. The technique exploits an intrinsic spatial distortion of the sensor that acquired the imagery and uses it as additional information to increase spatial resolution of the imagery. The method comprises obtaining a baseline image from the multidimensional imagery; deriving n×m−1 sub-pixel shifted images from the multidimensional imagery, where n and m are spatial resolution increase factors in x and y directions respectively, integers and greater than 1; organizing the baseline image and the n×m−1 sub-pixel shifted images from the multidimensional imagery; fusing the organized images using iterative back projection (IBP) to generate a high resolution image; and outputting the generated high resolution image.
