Local Threshold

Applies a threshold using the local neighborhood.
Radius
Standard deviation of gaussian neighborhood average for computing local contrast. If 0 is used a global threshold is used instead of one based on local contrast.

Antialiasing
Rough target of levels of accuracy for antialiasing, 1 to disable antialiasing.

Low
Thresholding level, 0.5 towards 0 to minimize shadows and towards 1.0 to minimize highlights.

High
Maximum values to include, above this gets set to 0.
