ABSTRACT:
Flash image orb artifacts arising from specular reflections from airborne particles are corrected. An image of a scene using flash illumination and a reference image of substantially the same scene are acquired. The reference and flash images are subtracted to generate a difference image. Edge and interior region features of an orb artifact within the difference image are determined. The edge feature is matched with the interior region, and the orb artifact is corrected from the flash image based on the matching.
