Abstract
Image data for an image frame are allocated among three groups. In one group are image data which are part of a derived motion boundary, along with image data which differ by at least a threshold amount from a corresponding point among normalized background data. In another group are image data which closely correspond to the normalized background image data. A third group includes the remaining pixels. An initial estimate for the object boundary is adjusted iteratively based on the groupings, followed by application of an active contour model.
