Description
Summary
Perform histogram equalization. If this seems to be doing nothing, try increasing the number of histograms bins by an order of magnitude or two (or more). Or, use "unu gamma" to warp the values in the direction you know they need to go. Either of these might work because extremely tall and narrow peaks in the equalization histogram will produce poor results.

Bins: the number of bins to use in histogram that is created in order to calculate the mapping that achieves the equalization. (int)
SBins: the number bins in value histogram to ignore in calculating the mapping. Bins are ignored when they get more hits than other bins, and when the values that fall in them are constant. This is an effective way to prevent large regions of background value from distorting the equalization mapping. default: "0"
Amount: extent to which the histogram equalizing mapping should be applied; 0.0: no change, 1.0: full equalization (float); default: "1.0"
