Lucid.Spectra.BaselineCorrection

Perform baseline correction using one of the following methods:

• poly: polynomial fitting.

• poly-iter: “Automated Method for Subtraction of Fluorescence from Biological Raman Spectra”, Lieber and Mahadevan-Jansen 2003, Applied Spectroscopy.

• unispline: univariate spline.

• exp: exponential background.

• log: logarithmic background.

• rubberband: rubberband baseline fitting.

• als: “Baseline Correction with Asymmetric Least Squares Smoothing”, Eilers and Boelens 2005.

• arPLS: “Baseline correction using asymmetrically reweighted penalized least squares smoothing”, Baek et al. 2015, Analyst 140: 250-257.

• drPLS: “Baseline correction method based on doubly reweighted penalized least squares”, Xu et al., Applied Optics 58(14):3913-3920.
