Actually, considering that my background lies in electrical engineering
I'd be more than happy to focus on the `signal` module. And from the
other response it seems like cythonizing `ndimage` wouldn't be a good idea.

So there would be enough candidates for Cythonization in `scipy.signal`
to fit the scope of GSoC? I myself can only guess where this would be
wanted and useful.

It doesn't have to be Cythonizing either. I'd be happy to add missing
functionality to the `signal` module or rework stuff that needs it.
The content in
https://docs.scipy.org/doc/scipy-1.0.0/reference/roadmap.html#signal
doesn't seem to be a good fit for a GSoC project. The only thing I can
think of right now is to extend the API for and add more adaptive filters:
https://en.wikipedia.org/wiki/Adaptive_filter
Again, I'm not sure this is wanted or if I'm judging the need correctly.

If you guys have any ideas or wishes in that direction I'd be happy to
hear them.

Best regards,
Lars
