Cv2ApproxPolyDP Method (InputArray, OutputArray, Double, Boolean)

OpenCvSharp Class Library

Approximates contour or a curve using Douglas-Peucker algorithm

Namespace: OpenCvSharp.CPlusPlus
Assembly: OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

C++

Copy

public static void ApproxPolyDP(
	InputArray curve,
	OutputArray approxCurve,
	double epsilon,
	bool closed
)

Public Shared Sub ApproxPolyDP ( 
	curve As InputArray,
	approxCurve As OutputArray,
	epsilon As Double,
	closed As Boolean
)

public:
static void ApproxPolyDP(
	InputArray^ curve, 
	OutputArray^ approxCurve, 
	double epsilon, 
	bool closed
)

static member ApproxPolyDP : 
        curve : InputArray * 
        approxCurve : OutputArray * 
        epsilon : float * 
        closed : bool -> unit

Parameters

curve: Type: OpenCvSharp.CPlusPlusInputArray
The polygon or curve to approximate. Must be 1 x N or N x 1 matrix of type CV_32SC2 or CV_32FC2.
approxCurve: Type: OpenCvSharp.CPlusPlusOutputArray
The result of the approximation; The type should match the type of the input curve
epsilon: Type: SystemDouble
Specifies the approximation accuracy. This is the maximum distance between the original curve and its approximation.
closed: Type: SystemBoolean
The result of the approximation; The type should match the type of the input curve
