NamespacesEmgu.CVCvInvokecvAvgSdv(IntPtr, MCvScalar%, MCvScalar%, IntPtr)

www.emgu.com/wiki
The function cvAvgSdv calculates the average value and standard deviation of array elements, independently for each channel
Declaration Syntax
C#Visual BasicVisual C++
public static void cvAvgSdv(
	IntPtr arr,
	ref MCvScalar mean,
	ref MCvScalar stdDev,
	IntPtr mask
)
Public Shared Sub cvAvgSdv ( _
	arr As IntPtr, _
	ByRef mean As MCvScalar, _
	ByRef stdDev As MCvScalar, _
	mask As IntPtr _
)
public:
static void cvAvgSdv(
	IntPtr arr, 
	MCvScalar% mean, 
	MCvScalar% stdDev, 
	IntPtr mask
)
Parameters
arr (IntPtr)
The array
mean ( MCvScalar %)
Pointer to the mean value
stdDev ( MCvScalar %)
Pointer to the standard deviation
mask (IntPtr)
The optional operation mask
Remarks
If the array is IplImage and COI is set, the function processes the selected channel only and stores the average and standard deviation to the first compoenents of output scalars (M0 and S0).
