Mat.ApproxPolyDP Method

MatApproxPolyDP Method

OpenCvSharp Class Library

Approximates contour or a curve using Douglas-Peucker algorithm. The input is the polygon or curve to approximate and it must be 1 x N or N x 1 matrix of type CV_32SC2 or CV_32FC2.

)

Public Function ApproxPolyDP ( 
	epsilon As Double,
	closed As Boolean
) As Mat

public:
Mat^ ApproxPolyDP(
	double epsilon, 
	bool closed
)

member ApproxPolyDP : 
        epsilon : float * 
        closed : bool -> Mat

Parameters

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

Return Value

Type: Mat
The result of the approximation; The type should match the type of the input curve
