This repository exists only for historical reason. If interested in Spectral Graph Wavelet Transform or in Graph Signal Processing in General, please check the PyGSP package (https://pygsp.readthedocs.io/).
Python implementation of the Spectral Graph Wavelet Transform (SGWT) [1].
The code is a port of the MATLAB implementation provided by the authors (available at http://wiki.epfl.ch/sgwt). The original code is released under GPLv3, so I guess this code should have the same license (I am not sure about this at the moment, the point seems to be moot. See [2] and [3] and for instance.)
