Cv2ConvexHull Method (IEnumerablePoint2f, Boolean)

Computes convex hull for a set of 2D points.

Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0

Syntax

public static Point2f[] ConvexHull(
	IEnumerable<Point2f> points,
	bool clockwise = false
)

Public Shared Function ConvexHull ( 
	points As IEnumerable(Of Point2f),
	Optional clockwise As Boolean = false
) As Point2f()

public:
static array<Point2f>^ ConvexHull(
	IEnumerable<Point2f>^ points, 
	bool clockwise = false
)

static member ConvexHull : 
        points : IEnumerable<Point2f> * 
        ?clockwise : bool 
(* Defaults:
        let _clockwise = defaultArg clockwise false
*)
-> Point2f[]

Parameters

points: Type: System.Collections.GenericIEnumerablePoint2f
The input 2D point set, represented by CV_32SC2 or CV_32FC2 matrix
clockwise (Optional): Type: SystemBoolean
If true, the output convex hull will be oriented clockwise, otherwise it will be oriented counter-clockwise. Here, the usual screen coordinate system is assumed - the origin is at the top-left corner, x axis is oriented to the right, and y axis is oriented downwards.

Return Value

Type: Point2f
The output convex hull. It is a vector of points that form the hull (must have the same type as the input points).
