Raman Spectrum Baseline Removal

Estimates the baseline and corrected spectrum of a given Raman spectrum.

function [base corrected_spectrum]=baseline(Spectrum)

This functions estimate the baseline and corrected spectrum of a a given Raman spectrum. Parts of the algorithm are similar to H. Schulze et al [1], but other parts have major differences.

Input:

Spectrum: vector of size (N*1)

Output:

Base: Identified Baseline vector of size (N*1)

Corrected_Spectrum: Corrected Spectrum vector of size (N*1)

Example on how to use the function is also provided.
