ImageTColor, TDepthThresholdAdaptive Method
http://www.emgu.com
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.

Namespace:  Emgu.CV
Assembly:  Emgu.CV.World (in Emgu.CV.World.dll) Version: 3.3.0.2824 (3.3.0.2824)
