Cv2.MeanStdDev Method (InputArray, Scalar, Scalar, InputArray)

Cv2MeanStdDev Method (InputArray, Scalar, Scalar, InputArray)

OpenCvSharp Class Library

computes mean value and standard deviation of all or selected array elements

Namespace: OpenCvSharp.CPlusPlus
Assembly: OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

C++

Copy

public static void MeanStdDev(
	InputArray src,
	out Scalar mean,
	out Scalar stddev,
	InputArray mask = null
)

Public Shared Sub MeanStdDev ( 
	src As InputArray,
	<OutAttribute> ByRef mean As Scalar,
	<OutAttribute> ByRef stddev As Scalar,
	Optional mask As InputArray = Nothing
)

public:
static void MeanStdDev(
	InputArray^ src, 
	[OutAttribute] Scalar% mean, 
	[OutAttribute] Scalar% stddev, 
	InputArray^ mask = nullptr
)

static member MeanStdDev : 
        src : InputArray * 
        mean : Scalar byref * 
        stddev : Scalar byref * 
        ?mask : InputArray 
(* Defaults:
        let _mask = defaultArg mask null
*)
-> unit

Parameters

src: Type: OpenCvSharp.CPlusPlusInputArray
The source array; it should have 1 to 4 channels (so that the results can be stored in Scalar's)
mean: Type: OpenCvSharp.CPlusPlusScalar
The output parameter: computed mean value
stddev: Type: OpenCvSharp.CPlusPlusScalar
The output parameter: computed standard deviation
mask (Optional): Type: OpenCvSharp.CPlusPlusInputArray
The optional operation mask
