Class GammaCorrection

java.lang.Object

org.openimaj.image.processing.algorithm.GammaCorrection

All Implemented Interfaces:

PixelProcessor<Float>

public class GammaCorrection
extends Object
implements PixelProcessor<Float>

Class to perform Gamma correction on a grey-level image. Grey levels are transformed such that I_new = I^Gamma for Gamma > 0 and all pixels I. If Gamma == 0 then the transform is I_new = log(I).
