Abstract
One embodiment of the present invention provides a system that determines a background image for a sequence of image frames. During operation, the system receives a sequence of input image-frames, wherein an input image-frame associates pixels with pixel-attributes. The system then computes a labeling, wherein the labeling associates pixels in the output background image with input image-frames in the sequence of input image-frames. Next, the system determines the output background image using the sequence of input image-frames and the labeling.
