WaveletImagePlot

WaveletImagePlot[dwd] plots the basis tree of wavelet image coefficients in the DiscreteWaveletData dwd.

• WaveletImagePlot[dwd, r] plots coefficients up to refinement level r.
• WaveletImagePlot[dwd, r, ifunc] applies the image function ifunc to coefficients and wavelet indexes before plotting.

Examples

Plot wavelet decomposition:

img = ExampleData[{"TestImage", "Lena"}];
dwd = DiscreteWaveletTransform[img];
WaveletImagePlot[dwd]

Limited refinement level:

WaveletImagePlot[dwd, 2]

With image function:

WaveletImagePlot[dwd, 3, ImageAdjust]
