| Abstract: A technique for computer vision uses a polygon contour to trace an
object. The technique includes rendering a polygon contour superimposed
over a first frame of image data. The polygon contour is iteratively
refined to more accurately trace the object within the first frame after
each iteration. The refinement includes computing image energies along
lengths of contour lines of the polygon contour and adjusting positions
of the contour lines based at least in part on the image energies. |
