Interface JHistogram

public interface JHistogram
extends Histogram

A histrogram interface for describing intensity levels in an image by use of a histogram. Histogram bins start at the intensity minimum and end at the maximum. There is no rule for prescribing the number of bins that a histogram may have, but the actual bin width in intensity can be queried with Histogram.getBinWidth(). To work together neathly with FITS images, that also support double pixel, we base calculations on doubles rather thatn float which would be more appropriate if working together with BufferedImageOp.

Nested Class Summary

static interface

JHistogram.Bounds Represents an upper and lower level in intensity.

Method Summary

JHistogram.Bounds	getBounds(double keep) Returns the upper and lower intensity value between which the stated number of pixel is situated.
JHistogram.Bounds	getModeBounds(double lo, double hi) Returns a mode bound, the given number of standard deviations from the mode.
JHistogram.Bounds	getNonsaturatedBounds(double keep) Returns the upper and lower intensity if saturation should be ignored.
JHistogram.Bounds	getUpperBounds(double keep) Returns the upper and lower intensity value between which the stated number of pixel is situated.
