Function Documentation

BaselineIModPoly()

const std::vector< double > sablib::BaselineIModPoly	(	const std::vector< double > &	y,
		const unsigned int	polyorder,
		const double	k = 1,
		const unsigned int	loop = 50,
		const double	eps = 1.0e-3 )

Estimates the baseline using the Improved Modified Polynomial (IModPoly) method.

Parameters

y	The input data points to be processed.
polyorder	The order of the polynomial to fit.
k	Scaling factor for the standard deviation threshold (default is 1.0).
loop	The maximum number of iterations (default is 50).
eps	The convergence tolerance based on the standard deviation change (default is 1.0e-3).

Returns

A vector containing the estimated baseline.

Exceptions

std::invalid_argument

One or more parameters are wrong.
