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:

WaveletImagePlot[
 DiscreteWaveletTransform[
  Image[Table[Sin[i/10] Cos[j/10], {i, 64}, {j, 64}]]]]

Limited refinement level:

WaveletImagePlot[
 DiscreteWaveletTransform[
  Image[Table[Sin[i/10] Cos[j/10], {i, 64}, {j, 64}]]], 2]

With image function:

WaveletImagePlot[
 DiscreteWaveletTransform[
  Image[Table[Sin[i/10] Cos[j/10], {i, 64}, {j, 64}]]], 3, ImageAdjust]
