peak detectors

Something I had in mind at some point is a peak detection based on
wavelets, but I did not find the time to finish that.
In my notes, I have this repository
https://github.com/johnmgregoire/PyWaveletPeakID which contains a code
working with pywavelet and a link to the paper. They got nice results on
a very noisy signal. Might not be universal, but useful for sure.

As you may know, I worked a bit with Ralf (Ralf did more than I) to
clean up pywavelet (mainly documentation, coding style, API). Ralf has a
clone on his github page. Pywavelet is not maintained anymore by its
original author. The next step is to integrate the code to scipy but we
need to find somebody who wants to play with C-python bindings. (The
last Gsoc project on that was not accepted). Definitely something that
would be useful to scikit-image and probably many other users.

Best,
