WebThe DELTA value controls how much difference between values in the TimeSeries defines an extremum point. Inside the function, we iterate over the data values of TimeSeries and consider a point to be a local maxima if it has the maximal value, and was preceded (to the left) by a value lower by DELTA. Similar logic applies to find a local minima. WebFind peaks in a 1-D array with wavelet transformation.
