Abstract
A system and method for correcting oversaturated pixels in far-infrared (FIR) images captured by a shutterless FIR camera. The method includes identifying oversaturated pixels based on a pixel value analysis of an input image; creating an oversaturated pixel mask of the input image, where the oversaturated pixel mask includes the identified oversaturated pixels and excludes pixels not identified as oversaturated pixels; and correcting the oversaturated pixels of the current image using the oversaturated pixel mask, based on a scene-based nonuniformity correction (SBNC).
