java.lang.Object

boofcv.alg.denoise.wavelet.DenoiseVisuShrink_F32

All Implemented Interfaces:

DenoiseWavelet<GrayF32>

public class DenoiseVisuShrink_F32
extends java.lang.Object
implements DenoiseWavelet<GrayF32>

Classic algorithm for wavelet noise reduction by shrinkage with a universal threshold. Noise is reduced by applying a soft threshold to wavelet coefficients. A method is provided for automatically selecting a reasonable threshold based upon the coefficients statistics.
