An optimization-based derivative-free line search method is developed to locate all the cornerpoints of two-dimensional polygon images for pattern recognition and inspection purposes. This optimization-based method is also used to approximate a two-dimensional non-polygon object by a polygon to any desired accuracy. The computation time of the proposed method is less than 10% of that required by other well-known methods.
