Detailed Description

Class to identify noise region and compute noise SD in spectra. Uses average magnitude spectrum to first identify region with smallest SD. This region is likely to be noise rather than signal. Once the region is defined, the noise SD is computed as an average value of noise SD computed at each voxel over the identified frequency range.

float GetPeakArea	(	vtkFloatArray *	spectrum,
		int	peakNum
	)

Returns the real valued peak height in the range defined for the specified peak number.

void GetPeakDefinition	(	int	peakNum,
		int *	startPt,
		int *	peakPt,
		int *	endPt
	)

prints peak definition

float GetPeakHeight	(	vtkFloatArray *	spectrum,
		int	peakNum
	)

Returns the real valued peak height in the range defined for the specified peak number.

float GetPeakHeightAtPeakPos	(	vtkFloatArray *	spectrum,
		int	peakNum
	)

Returns the real valued peak height in the range defined for the specified peak number.

float GetPeakSymmetry	(	vtkFloatArray *	spectrum,
		int	peakNum

void SetBaselineValue ( float baseline )

Get the mean value of the baseline in the window used for SD calc.

void SetNoiseSD ( float noise )

Set the noise SD

Referenced by svkMRSPeakPick::RequestData().

void SetResolutionHeightFraction ( float resolveHeightFraction )

Set the fractional resolve height. For example, does a peak need to be resolved at fwhh to be detected. If so set to 0.5. If the peak only needs to be resolved at 0.7 of max then set to 0.7.
