We say that an element arr [x] is a local minimum if it is less than both its neighbors. For corner elements, we need to consider only one neighbor for comparison. There can be more than one local minima in an array, we need to find one of them.
Web1. Assuming some statistical representation of your data you should be able to perform a 3D local max like this. Hopefully this answers your question. import numpy as np import scipy.ndimage as ndimage img = np.random.normal (size= (100, 256, 256)) # Get local maximum values of desired neighborhood # I'll be looking in a 5x5x5 area img2 ... 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.
