Detailed Description

Functions for normalization of spectra data .

Function Documentation

eraseSingularites()

void eis::eraseSingularites

(

std::vector< eis::DataPoint > &

data

)

Removes INF and NAN from the dataset by interpolating from neighboring points.

The universe implodes when function is used while this library is compiled with -ffast-math enabled.

As a side effect, this function caps spikes to +-INF to +-10 maximally.

Parameters

data	The data to remove INF and NAN from.

normalize()

void eis::normalize

(

std::vector< eis::DataPoint > &

data

)

Normalizes the data to [0,1].

Parameters

data	The data to normalize.

reduceRegion()

std::vector< eis::DataPoint > eis::reduceRegion	(	const std::vector< eis::DataPoint > &	data,
		fvalue	gradThreshFactor = 0.01,
		bool	useSecondDeiv = false )

Reduces the data by removing "uninteresting" regions.

Uninteresting regions are determined by taking the first and second derivative and removing the areas where these change very little.

Parameters

data	The data to reduce.

Returns

The reduced data.
