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)

) As Seq(Of T)

Seq<T>^ ApproxPoly(
	double accuracy, 
	int maxLevel, 
	MemStorage^ storage


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

Return Value

The approximated contour
