Class ConvexHull

java.lang.Object

imagingbook.pub.regions.geometry.ConvexHull

public class ConvexHull
extends Object

This class serves to calculate the convex hull of a binary region or a closed contour, given as a sequence of point coordinates. It is based on the convex hull implementation provided by the Apache Commons Math library, in particular the classes ConvexHull2D and MonotoneChain. If a region provides an outer contour, then this is used for the convex hull computation, otherwise the entire (inner) region is used.
