COMPOSITING GRAPHICAL OBJECTS

Computer programs and computer-implemented methods implement techniques for rendering an image. A target area is identified in the image and a set of pixels to sample is selected from the target area to sample. An attribute value is identified for each of a plurality of the pixels in the selected set, and an attribute value is predicted for the target area based on the identified attribute value. At least a portion of the foreground area can be rendered based on the predicted attribute value. In preferred embodiments, a statistical sampling analysis is used to predict a background color when rendering a foreground area of an image.
