Volumetric wavelet Data Processing - MathWorks

https://in.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/9554/versions/5/previews/numerical-tour/multidim_volumetric/index.html

Similarely to the Haar transform, wavelets with more vanishing moments are obtained with filtering and subsampling (pyramidal algorihtm). First we create the filters for 4 vanishing moments. [h,g] = compute_wavelet_filter('Daubechies',2*4); Then we initialize the wavelet transform with the 3D image itself, and set the current scale.
