Transforms grayscale image to binary image. Threshold calculated individually for each pixel. For the method CV_ADAPTIVE_THRESH_MEAN_C it is a mean of blockSize x blockSize pixel neighborhood, subtracted by param1. For the method CV_ADAPTIVE_THRESH_GAUSSIAN_C it is a weighted sum (gaussian) of blockSize x blockSize pixel neighborhood, subtracted by param1.

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.
maxValue
Type: System..::..Double
Maximum value to use with CV_THRESH_BINARY and CV_THRESH_BINARY_INV thresholding types
adaptiveType
Type: Emgu.CV.CvEnum..::..ADAPTIVE_THRESHOLD_TYPE
Adaptive_method
thresholdType
Type: Emgu.CV.CvEnum..::..THRESH
Thresholding type. must be one of CV_THRESH_BINARY, CV_THRESH_BINARY_INV
blockSize
Type: System..::..Int32
The size of a pixel neighborhood that is used to calculate a threshold value for the pixel: 3, 5, 7, ...
param1
Type: System..::..Double
Constant subtracted from mean or weighted mean. It may be negative.
