Two common measures are the Minimum Convex Polygon and the Reock scores. Minimum Convex Polygon is the ratio of the area of a shape to its convex hull.
WebThe complexity measure provides a quantitative description of the polygon shape. It can be used as an input for other geometric algorithms, or to find out if any algorithm depends on the geometric complexity of input polygons in terms of speed or quality of outputs.
