title = "Identification of cornerpoints of two-dimensional images using a line search method",
abstract = "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.",

note = "Funding Information: Suppose the boundary information of a two-dimensional image suffices for pattern recognition or parts inspection for a certain class of part types . When the boundary is piecewise linear, the identification of cornerpoints on the boundary is usually sufficient for visual inspection . Once the cornerpoints of an image boundary are determined, it is simple to determine the length of a line segment connecting two adjacent cornerpoints and also the angle between two line segments which are adjacent to a cornerpoint . When the boundary of the image is not piecewise linear, the curved boundary can be approximated by polylines . These polygonal images, exact or approximated, are useful not only for inspection purposes but also for identifying those part types involved in an overlapped imag.et 2 j {"}This work was partially supported by the Engineering Excellence Fund of Texas A&M University .",
