Peak detection on signals in Python

Thanks for the nice article. Peak detection algorithms are indeed required in many engineering applications, so it is good to see that there are different approaches to the same problem.

I just want to add that PeakUtils also support fitting gaussians and computing centroids to increase the peak resolution, allowing for a higher resolution (instead of just finding the indexes). Also, the PeakUtils indexes function was inspired on Marcos Duarte implementation, so those methods have some similarities in the results.

I've editted the post to add a note on these points, thanks for the feedback!

Great article. For your application, you would maybe be interested in a small and fast findpeaks implementation I coded a while ago: https://github.com/jankoslavic/py-tools/tree/master/findpeak...

Thanks, it works great, added to the list: https://github.com/MonsieurV/py-findpeaks#janko-slavic-findp...

Good info. I had to solve this problem a couple of weeks ago and ended up coding up my own solution.

I had to calculate (well, estimate) the SNR of signals for which I had little useful information. So, I needed to isolate the 'signal' (my signals had only one peak) from the rest of the waveform to get an estimate for the noise. Bah, not fun.
