Class Equalizer

java.lang.Object
  extended by ij.plugin.filter.Equalizer
All Implemented Interfaces:
PlugInFilter

public class Equalizer
extends java.lang.Object
implements PlugInFilter

Implements ImageJ's Equalize command. It changes the tone curves of images. It should bring up the detail in the flat regions of your image. Histogram Equalization can enhance meaningless detail and hide important but small high-contrast features. This plugin uses a similar algorithm, but uses the square root of the histogram values, so its effects are less extreme. Hold the alt key down, or set 'arg' to "classic", to use the standard histogram equalization algorithm. This code was contributed by Richard Kirk (rak@cre.canon.co.uk).

setup

public int setup(java.lang.String arg,
                 ImagePlus imp)
Set 'arg' to "classic" to use the standard histogram equalization algorithm.

setup in interface PlugInFilter

run

public void run(ImageProcessor ip)
Description copied from interface: PlugInFilter
Filters use this method to process the image. If the SUPPORTS_STACKS flag was set, it is called for each slice in a stack. Image/J will lock the image before calling this method and unlock it when the filter is finished.
