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%|          | 0/50 [00:00<?, ?it/s]
  2%|▏         | 1/50 [00:03<03:03,  3.75s/it]
 26%|██▌       | 13/50 [00:04<00:09,  3.81it/s]
 30%|███       | 15/50 [00:05<00:09,  3.51it/s]
 78%|███████▊  | 39/50 [00:05<00:00, 13.71it/s]
100%|██████████| 50/50 [00:05<00:00,  9.31it/s]

Plot the signal and its baseline:

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