A method and system for segmenting foreground objects in digital video is disclosed. Implementation of this technology facilitates object segmentation in the presence of shadows and camera noise. The system may include a background registration component for generating a background reference image from a sequence of digital video frames. The system may also include a gradient segmentation component and a variance segmentation component for processing the intensity and chromatic components of the digital video to determine foreground objects and produce foreground object masks. The segmentation component data may be processed by a threshold-combine component to form a combined foreground object mask. The method for segmenting foreground objects may include identifying a background reference image for each video signal from the digital video, subtracting the background reference image from each video signal component of the digital video to form a resulting frame, and processing the resulting frame associated with the intensity video signal component with a gradient filter to segment foreground objects and generate a foreground object mask.
