1. A computer-implemented method for tracking foreground objects depicted in a scene, the method comprising:

  • receiving a background/foreground BG/FG segmentation of a current video frame, wherein the current video frame includes one or more appearance values for each of a plurality of pixels and wherein the BG/FG segmentation classifies one or more of the pixels as depicting either scene foreground or scene background;

    for each region of pixels in the current frame classified as depicting scene foreground, determining an ellipse to bound the region;

    classifying at least a first one of the ellipses as corresponding to a first known foreground object tracked in at least a prior frame; and

    extending a trajectory of the first known foreground object based on the appearance values of the pixels bound by the first ellipse.
