Abstract
An adaptive method for removing fixed pattern noise from focal plane array (FPA) imagery. A set of correction terms (26) is applied to the focused image from the FPA, and a filter (24C) is applied to the corrected, focused image. The set of correction terms is also applied to a blurred version of the FPA image, and the filter is applied to the corrected, blurred image. Fixed pattern noise errors are then calculated using the filtered imagery, and employed to update the correction terms. The updated correction terms are then used for processing the next image. In one embodiment, the filter is an antimedian filter. In another embodiment, the filter is an anti-mean filter.
