Catalano.Imaging.Tools.ColorMoments

public class ColorMoments
extends java.lang.Object

Color Moments. Color moments are measures that can be used differentiate images based on their features of color. These moments provide a measurement for color similarity between images. These values of similarity can then be compared to the values of images indexed in a database for tasks like image retrieval.
