Abstract
The present disclosure includes, among other things, systems, methods and program products for generating a clean reference frame image. A method includes obtaining a color census of a color image. A color profile is selected based on the color census. One or more foreground areas of the image are identified, the foreground areas comprising image areas containing colors that do not fit the color profile. For each identified foreground area, a color is applied to the identified foreground area based on one or more colors of one or more non-identified image areas to create a clean reference image.
