Enumeration Type Documentation

Enumerator
Simple 

Simple upper and lower usage thresholds are applied to the values in each channel's histogram to determine the input start/stop points for each individual channel. The start/stop points are used to calcualte the scale factor and offset for the channel.

Area 

Threshold is applied based on cumulative area at the lower and upper ends of the histogram. Much larger thresholds are required for this than SimpleThreshold.

GIMP 

Threshold is applied based on strangely skewed cumulative area, identical to the process used by GIMP
