Abstract
A method for restoring and enhancing a space based image of point or spot objects. The method includes: 1) dividing a space-variable degraded image into multiple space-invariant image sub-blocks, and constructing a point spread function for each of the image sub-blocks; 2) correcting each of the image sub-blocks via a space-invariant image correction method whereby obtaining a corrected image {circumflex over (f)}for each of the image sub-blocks; and 3) stitching the corrected image sub-blocks {circumflex over (f)}altogether via a stitching algorithm whereby obtaining a complete corrected image {circumflex over (f)}.
