NamespacesEmgu.CVCvInvokecvCreateContourTree(IntPtr, IntPtr, Double)

www.emgu.com/wiki
Creates binary tree representation for the input contour and returns the pointer to its root.
Declaration Syntax
C#Visual BasicVisual C++
public static IntPtr cvCreateContourTree(
	IntPtr contour,
	IntPtr storage,
	double threshold
)
Public Shared Function cvCreateContourTree ( _
	contour As IntPtr, _
	storage As IntPtr, _
	threshold As Double _
) As IntPtr
public:
static IntPtr cvCreateContourTree(
	IntPtr contour, 
	IntPtr storage, 
	double threshold
)
Parameters
contour (IntPtr)
Input contour
storage (IntPtr)
Container for output tree
threshold (Double)
If the parameter threshold is less than or equal to 0, the function creates full binary tree representation. If the threshold is greater than 0, the function creates representation with the precision threshold: if the vertices with the interceptive area of its base line are less than threshold, the tree should not be built any further
Return Value
The binary tree representation for the input contour
