摘要
A previous paper described a method of extracting long sequences of border points from images of mechanical parts, by linking points having high edge values that lie on the borders of thresholded regions. This paper develops methods of fitting polygons and arcs of ellipses to the border sequences. The results are applied to finding small holes in images of connecting rods. © 1979.
