An image segmentation method and apparatus are described. The inventive system and apparatus generates a segmented image of an occupant or other target of interest based upon an ambient image, which includes the target and the environment in the vehicle that surrounds the target. The inventive concept defines a bounding ellipse for the target. This ellipse may be provided to a processing system that performs tracking of the target. In one embodiment, an optical flow technique is used to compute motion and illumination field values. The explicit computation of the effects of illumination dramatically improves motion estimation and thereby facilitates computation of the bounding ellipses.
