Assembly: Emgu.CV (in Emgu.CV.dll) Version: 2.3.0.1416 (2.3.0.1416)
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.
