Applies fixed-level thresholding to single-channel array. The function is typically used to get bi-level (binary) image out of grayscale image or for removing a noise, i.e. filtering out pixels with too small or too large values. There are several types of thresholding the function supports that are determined by thresholdType

static double Threshold(
	IntPtr src, 
	IntPtr dst, 
	double threshold, 
	double maxValue, 
	THRESH thresholdType, 
	IntPtr stream
)

Parameters

src
Type: System..::..IntPtr
Source array (single-channel, 8-bit of 32-bit floating point).
dst
Type: System..::..IntPtr
Destination array; must be either the same type as src or 8-bit.
threshold
Type: System..::..Double
Threshold value
maxValue
Type: System..::..Double
Maximum value to use with CV_THRESH_BINARY and CV_THRESH_BINARY_INV thresholding types
thresholdType
Type: Emgu.CV.CvEnum..::..THRESH
Thresholding type
stream
Type: System..::..IntPtr
Use a Stream to call the function asynchronously (non-blocking) or IntPtr.Zero to call the function synchronously (blocking).
