	InputArray src,
	OutputArray dst,
	double thresh,
	double maxval,
	ThresholdType type
)

Public Shared Function Threshold ( 
	src As InputArray,
	dst As OutputArray,
	thresh As Double,
	maxval As Double,
	type As ThresholdType
) As Double

public:
static double Threshold(
	InputArray^ src, 
	OutputArray^ dst, 
	double thresh, 
	double maxval, 
	ThresholdType type
)

static member Threshold : 
        src : InputArray * 
        dst : OutputArray * 
        thresh : float * 
        maxval : float * 
        type : ThresholdType -> float

Parameters

src: Type: OpenCvSharp.CPlusPlusInputArray
input array (single-channel, 8-bit or 32-bit floating point).
dst: Type: OpenCvSharp.CPlusPlusOutputArray
output array of the same size and type as src.
