All Implemented Interfaces:

IApplyInPlace

public class HomomorphicFilter
extends java.lang.Object
implements IApplyInPlace

Is a frequency domain filtering process that compresses the brightness, while enhancing the contrast. Homomorphic filtering process: Image -> A natural log transform (base e) -> Fourier Transform -> Frequency filter -> Inverse Fourier Transform -> Inverse log function (the exponencial).
