cvApproxPoly Method (src_seq, header_size, storage, method, parameter, parameter2)

www.emgu.com/wiki

Approximates one or more curves and returns the approximation result[s]. In case of multiple curves approximation the resultant tree will have the same structure as the input one (1:1 correspondence).

Declaration Syntax

Visual Basic

Visual C++

public static IntPtr cvApproxPoly(
	IntPtr src_seq,
	int header_size,
	IntPtr storage,
	APPROX_POLY_TYPE method,
	double parameter,
	int parameter2
)

Public Shared Function cvApproxPoly ( _
	src_seq As IntPtr, _
	header_size As Integer, _
	storage As IntPtr, _
	method As APPROX_POLY_TYPE, _
	parameter As Double, _
	parameter2 As Integer _
) As IntPtr

public:
static IntPtr cvApproxPoly(
	IntPtr src_seq, 
	int header_size, 
	IntPtr storage, 
	APPROX_POLY_TYPE method, 
	double parameter, 
	int parameter2
)

Parameters

src_seq (IntPtr): Sequence of array of points

header_size (Int32): Header size of approximated curve[s].

storage (IntPtr): Container for approximated contours. If it is NULL, the input sequences' storage is used

method (APPROX_POLY_TYPE): Approximation method

parameter (Double): Desired approximation accuracy

parameter2 (Int32): If case if src_seq is sequence it means whether the single sequence should be approximated or all sequences on the same level or below src_seq (see cvFindContours for description of hierarchical contour structures). And if src_seq is array (CvMat*) of points, the parameter specifies whether the curve is closed (parameter2!=0) or not (parameter2=0).

Return Value

the approximation result
