Detailed Description
SoThresholdingProcessing engine
The SoThresholdingProcessing engine transforms a grayscale image into a binary image.
For an introduction, see section Binarization.
The SoThresholdingProcessing engine thresholds a grey level image. In the output binary image, all pixels with an initial grey level value lying between the two bounds are set to 1, all the other pixels are set to 0.
The SoThresholdingProcessing engine produces a binary image between two levels 
and 
. Threshold with 2 bounds is the default, but a threshold with a single bound may be achieved by setting or to the values 0 or 255, respectively. The definition is:
![\[O(n,m)=\begin{Bmatrix} 1 & \mbox {if & \lambda_1 \leq I(n,m) \leq \lambda_2} \\ 0 & \mbox{if & I(n,m)<\lambda_1 or I(n,m)>\lambda_2} \end{matrix}\]](form_526.png)
