Device for displaying feature of contour image

摘要: The x-y coordinates are determined of a multiplicity points set at very small intervals fixed value on contour line, the selected number either side one (central point) aforementioned averaged, two corresponding to sets averaged connected by straight perpendicular line is drawn this from central point, and distance point foot calculated. This varies with change in shape line. By finding respect each displaying distances found, there can be obtained figure indicative features image.
