Peak detection algorithm in Python

python - How to find and visually mark the local minima of a sequence?

QUESTION

Peak detection algorithm in Python

Asked 2019-Dec-10 at 08:54

I'm implementing a peak detection algorithm in Python that detects only those peaks that are above a threshold magnitude. I don't want to use the inbuilt function as I have to extend this simulation to Hardware implementation also.

So, here you have a numpythonic solution (which is much better than doing a loop explicitly).

I use the roll function to shift the numbers +1 or -1 in the position. Also a "peak" is defined as a local maximum, where the previous and posterior number are smaller than the central value.

The full code is:

QUESTION

python - How to find and visually mark the local minima of a sequence?

Asked 2019-Dec-04 at 01:05

How to draw a sequence of points with increasing local minima and mark them with another color? Something similar as in the picture. I am not able to set a list with that sequence and the minima are wrong. Or is there an easier way to do that?

I tried this code:

Try scipy.signal.find_peaks. To find minima's you multiply series by -1.

find_peaks returns the indices of peaks or minima. To get the correct plotting positions, you have to index x and series with the output from find_peaks.

If you are concerned about your singal containing sequences of decreasing minima, you could compare the magnitudes of sequential peaks using np.diff.
