Abstract
A method for combining a first digital image and a second background digital image, both images including pixels having color values, wherein the first digital image includes both a foreground region having foreground color values and a key color region characterized by a key color, as well as a mixed region where the pixel color values are a mixture of the foreground color value and the key color, includes determining a first control signal that indicates the relative proportions of the foreground color value and the key color for pixels in the first digital image; and segmenting the first digital image into a key color region and a non-key color region in which the non-key color region includes pixels in the first digital image that are not in the key color region. The method also includes determining a second control signal that indicates a spatial distance between the pixels in the first digital image and a boundary between the key color region and the non-key color region; and combining the first digital image and the second background digital image in response to the first and second control signals, the key color, and an illuminant color value.
