All Implemented Interfaces:

public class Histogram<T extends RealType<T>>
extends TreeMap<Double,Integer>

An histogram of the image (or an image computed from an IFunction) between its minimum and maximum values, with as many bins as desired (defaults to 256 bins). The number of bins is then the TreeMap.size(), and the value of each bin (each element in this ArrayList) is an integer, which is the count of voxels whose value falls within the bin.
