Patent ID: 7933464

Claim:
A scene-based non-uniformity correction method employing super-resolution for eliminating fixed pattern noise in a video having a plurality of input images, comprising the steps of: (a) warping each of the plurality of images with respect to a reference image to obtain a warped set of images; (b) performing one of averaging and deblurring on the warped set of images to obtain an initial estimate of a reference true scene frame; (c) warping the initial estimate of the reference true scene frame with respect to each of the plurality of images to obtain a set of estimated the signal images; (d) performing a least square fit algorithm to estimate a gain image and an offset image given the set of estimated true signal images; (e) applying the estimated gain image and estimated offset image to the plurality of images to obtain a clean set of images; and (f) applying a super-resolution algorithm to the clean set of images to obtain a higher resolution version of the reference true scene frame.
