When using wavelet.cwt I get the following warning about a future deprecation in scipy:

/home/jorge/.local/lib/python3.5/site-packages/scipy/fftpack/basic.py:159: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use arr[tuple(seq)] instead of arr[seq]. In the future this will be interpreted as an array index, arr[np.array(seq)], which will result ei

I a hope I am not missing anything but I could not find the layout of the coefficient vector. Inspecting the size of the coefficient also does not immediately suggest a certain order to me.

According to scipy's documentation, ndimage.imread has been deprecated since v1.0 and removed in 1.2.0.

Can you please update the code to not use it?

Whenever a paper is mentioned, including the corresponding reference (i.e. full bibliography cite and/or link) would be nice.
See for example, the block
* \brief Wavelet based on paper VOW: Variance-Optimal Wavelets for Steerable Pyramid (P.Pad et al 2014).
in itkVowIsotropicWavelet.h.

On the other hand, formulas must follow Doxygen rules [1]. There are a few examples in ITK, such as
