1. A computer-implemented method for detecting motion in a sequence of video frames, the method comprising:

  • identifying residual pixels from the sequence of video frames, to provide estimated indication of a moving object or a static three-dimensional (3-D) structure; and

    sorting the identified residual pixels to isolate pixels that correspond to the moving object comprising;

    applying at least two geometric constraints to the identified one or more residual pixels, wherein the at least two geometric constraints represent at least a variation in relative depth of the residual pixels;

    detecting a disparity of the residual pixels to the applied at least two geometric constraints;

    based on the detected disparity, filtering the residual pixels to remove pixels that do not correspond to the moving object;
