org.lsst.ccs.utilities.image.patterns.NoisePatternGenerator

public class NoisePatternGenerator
extends PatternGenerator

A PatternGenerator that creates a random noise in a pixel block pattern varying from a baseline to a maximum amplitude in gray scale. The allowed parameters for this patternGenerator are: - noise_width: the width of the noise block in pixels - noise_ySize: the height of the noise block in pixels - noise_maxAmplitude: the maximum amplitude of the noise. An integer from 0 to 256 - noise_baseline: the noise baseline. An integer form 0 to 256 - ripples_frequency: the ripples frequency The idea for this code was taken from http://www.lac.inpe.br/JIPCookbook/1200-create-gl.jsp
