Function Documentation

BaselineBeads()

const std::tuple< std::vector< double >, std::vector< double > > sablib::BaselineBeads	(	const std::vector< double > &	y,
		const unsigned int	s,
		const double	frequency,
		const double	r,
		const double	lambda0,
		const double	lambda1,
		const double	lambda2,
		const unsigned int	loop = 30,
		const double	eps = 1e-3,
		const BeadsPenalty	penalty = BeadsPenalty::L1_v2 )

Performs baseline estimation and denoising using Sparsity (BEADS).

Parameters

y	The input data.
s	Order of the derivative for baseline sparsity (typically 1 or 2).
frequency	Sampling frequency of the signal.
r	High-pass filter parameter (cut-off frequency relative to sampling frequency).
lambda0	Sparsity parameter for the baseline.
lambda1	Sparsity parameter for the first-order derivative of the signal.
lambda2	Sparsity parameter for the second-order derivative of the signal.
loop	Maximum number of iterations.
eps	Convergence threshold.
penalty	Penalty type (L1_v1 or L1_v2).

Returns

A tuple containing (baseline, denoised signal).

Exceptions

std::invalid_argument

One or more parameters are wrong.
