Class MedianCut

java.lang.Object
  ij.process.MedianCut

public class MedianCut
extends java.lang.Object

Converts an RGB image to 8-bit index color using Heckbert's median-cut color quantization algorithm. Based on median.c by Anton Kruger from the September, 1994 issue of Dr. Dobbs Journal.

Constructor Summary

MedianCut(ColorProcessor ip)

MedianCut(int[] pixels, int width, int height)

Method Summary

java.awt.Image	convert(int maxcubes) Uses Heckbert's median-cut algorithm to divide the color space defined by "hist" into "maxcubes" cubes.
ImageProcessor	convertToByte(int maxcubes) This is a version of convert that returns a ByteProcessor.

                 int height)

MedianCut

public MedianCut(ColorProcessor ip)

Method Detail

convert

public java.awt.Image convert(int maxcubes)

Uses Heckbert's median-cut algorithm to divide the color space defined by "hist" into "maxcubes" cubes. The centroids (average value) of each cube are are used to create a color table. "hist" is then updated to function as an inverse color map that is used to generate an 8-bit image.

convertToByte

public ImageProcessor convertToByte(int maxcubes)

This is a version of convert that returns a ByteProcessor.
