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%| | 0/51 [00:00<?, ?it/s]
2%|▏ | 1/51 [00:04<03:33, 4.28s/it]
25%|██▌ | 13/51 [00:05<00:11, 3.36it/s]

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