The method generates a skeleton of a polygon by selecting a line segment or concave vertex (104) of the polygon and comparing it against the other line segments(106) in turn. The method determines (108,110,112), when comparing a selected line segment or concave vertex i with another line segment j, any significant parameter value associated with a point on selected line segment, where the locus(i,j) at that parameter value describes the skeleton.
