Claim One:
1. A method for increasing spatial resolution of a hyperspectral data cube imagery, the method comprising: extracting a single baseline image from the hyperspectral data cube imagery; deriving n×m−1 keystone induced sub-pixel shifted images from the hyperspectral data cube imagery, where n and m are integers and greater than 1; organizing the single baseline image and the n×m−1 sub-pixel shifted images that are derived from the hyperspectral data cube imagery into an organized image array having a 1/n, 2/n,. .. (n−1)/n pixel shift in horizontal direction and 1/m, 2/m,. .. (m−1)/m in vertical direction in relation to the single baseline image; fusing the organized image array using iterative back projection (IBP) to generate a finer resolution image; and outputting the generated finer resolution image.
