Threshold
As shown on next figure, a set of five parameters —LUT_SlicingLevel, LUT_SlicingBand, LUT_LightResponse, LUT_BandResponse, and LUT_DarkResponse— defines a double threshold transformation law. All parameters are "float collection" parameters, ranging from 0.00 up to 1.00.
These controls are applicable exclusively with the threshold parametric LUT definition method.
Threshold method
LUT_SlicingLevel specifies the mean value of both thresholds in the input range. The default value of 0.5 specifies the middle of the input range.
The following table lists the value ranges and default values:
