public class Compute_Histogram
extends Object
implements PlugInFilter, JavaDocHelp

ImageJ plugin which calculates and displays (lists) the histogram of a 8-bit grayscale image. See Sec. 2.3 of [1] for additional details. Alternatively the histogram could be obtained with ImageJs built-in method (see also Equalize_Histogram):

 int[] h = ip.getHistogram();
