New wavelet filters #11

Closed KevinAquino closed 4 years ago

KevinAquino commented 4 years ago

Hiya,

I'm loving the toolbox! I was wondering if you had plans to add in different wavelet families like the Haar or daubechies wavelets?

mdeff commented 4 years ago

Thanks for your kind words. :) This toolbox is not actively developed anymore: There's little chance anything will be added. However, if you want to contribute, there are good chances your PRs will be accepted. Alternatively, I encourage you to look at the python version, which is actively developed.

ah cool thanks! :)

By the way, graph filters requires a continuous scaling and wavelet functions. So daubechies should work but Haar not.

In any case, it should be relatively trivial to defines daubechies both in the python and the matlab versions.

mdeff commented 4 years ago

For the PyGSP, could we use PyWavelets instead of defining the wavelets ourselves?

KevinAquino commented 4 years ago

Thanks for the info! I might add in daubechies and send a PR :)

Great! Looking forward. :)
