MatConvexHullPoints Method
|
Computes convex hull for a set of 2D points.
Namespace:

Assembly:

Syntaxpublic Point[] ConvexHullPoints(
InputArray points,
bool clockwise = false
)
Public Function ConvexHullPoints (
points As InputArray,
Optional clockwise As Boolean = false
) As Point()
public:
array<Point>^ ConvexHullPoints(
InputArray^ points,
bool clockwise = false
)
member ConvexHullPoints :
points : InputArray *
?clockwise : bool
(* Defaults:
let _clockwise = defaultArg clockwise false
*)
-> Point[]
function ConvexHullPoints(points, clockwise);
Parameters
- points
- Type: OpenCvSharpInputArray
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:
PointThe output convex hull. It is a vector of points that form the
hull (must have the same type as the input points).
