virtual bool EightSED::getP (  const int  x, const int  y, int &  px, int &  py )  const [virtual]

return the "parent" (border point) associated with this point Parameters: x  is the x location y  is the y location px  is the parent's x location to be returned py  is the parent's y location to be returned Returns: true if the parent is know; otherwise false. Reimplemented from DistanceTransform.
