ABSTRACT:
A method, apparatus, and article of manufacture provide the ability to automatically reproduce film grain into a new image. A reference image and new image are obtained. An image of the reference image is subdivided into two or more tiles. A grain simulation tool is then used to automatically determine if an object feature exists in each of the two or more tiles. Response curves are constructed for each of the tiles that does not contain an object feature. Frames of grain are produced/generated based on the response curves and added to the new image.
