MultiscaleGraphSignalTransforms.jl is a collection of software tools written in the Julia programming language for graph signal processing including HGLET, GHWT, eGHWT, NGWP, Lapped NGWP, and Lapped HGLET. Some of them were originally written in MATLAB by Jeff Irion, but we added more functionalities, e.g., eGHWT, NGWP, etc.

This is the Julia package of Natural Graph Wavelet Packet Dictionaries.

Graph wedgelets for image compression

Signal processing on simplicial complexes, using basis dictionaries formed via hierarchical partitioning

This is the source code for implementing hyperedge representations via hypergraph wavelets.
