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)

	storage As MemStorage _
) As Contour(Of T)
Visual C++
Contour<T>^ ApproxPoly(
	double accuracy, 
	int maxLevel, 
	MemStorage^ storage


Type: System..::..Double
The desired approximation accuracy
Type: System..::..Int32
Maximal level for contour approximation. If 0, only contour is arrpoximated. If 1, the contour and all contours after it on the same level are approximated. If 2, all contours after and all contours one level below the contours are approximated, etc. If the value is negative, the function does not draw the contours following after contour but draws child contours of contour up to abs(maxLevel)-1 level
Type: Emgu.CV..::..MemStorage
The storage the resulting sequence use

Return Value

The approximated contour
