1. A method of determining an object contour in an image frame of a video employed in a video processing system, the method comprising:

  • determining a phase space representation of the image frame;

    selecting a phase space filter from a set of phase space filters according to an estimated size of the object, wherein the set of phase space filters comprises phase space filters having a plurality of different phase space scale responses;

    scaling the phase space representation using the selected phase space filter;

    discarding redundant points of the scaled phase space representation to form a filtered frame;

    comparing the filtered frame with a reference frame to determine an approximate object contour; and

    storing the approximate object contour on a computer readable medium.
