Baseline Removal

This example shows how to remove a baseline from a 1D signal using the pybaselines library.

Create a signal

import hyperspy.api as hs
s = hs.data.two_gaussians()

Remove baseline using remove_baseline():

s2 = s.remove_baseline(method="aspls", lam=1E7, inplace=False)

  0%|          | 0/2 [00:00<?, ?it/s]
 50%|█████     | 1/2 [00:09<00:09,  9.16s/it]
100%|██████████| 2/2 [00:09<00:00,  4.59s/it]

Plot the signal and its baseline:

(s + (s-s2) * 1j).plot()
# Choose the second figure as gallery thumbnail:
# sphinx_gallery_thumbnail_number = 2
