Class ColorDistance1

java.lang.Object
  org.shapelogic.color.ColorDistance1

All Implemented Interfaces:

IColorDistance

Direct Known Subclasses:

ColorDistance1RGB, ColorDistanceWithImage1

public class ColorDistance1
extends java.lang.Object
implements IColorDistance

ColorNorm is the scaled 1 norm in the color space.
The 1 norm is called the Taxicab norm or Manhattan norm.
It is then scaled down by the number of dimensions, so that the distance of 2 colors will be the same in gray and RGB space.

This could be changed to use scaling for the different component.

This should work for both color and gray.
