ABSTRACT:
A method and system for retouching digital images for a motion picture removes semi-transparent artifacts or ‘blotches’ caused by contaminates in the optical path of the camera. This approach provides the benefit of only having to retouch a single average image that is than automatically applied via a correction power map to the entire sequence of images for the affected scene. The formation of an average image tends to reinforce the artifacts making them easier to identify and reduce background detail making it easier to retouch the artifact.
