Detailed Description

Interface to compute various measures on tensors.

Prominent examples are the Fractional Anisotropy (FA), trace, Relative Anisotropy, Mean Diffusivity, Radial Diffusivity, etc. As many scalar measures may use either the tensor components directly or rely on derived measures such as eigenvalues, both are needed for generating the scalar.

◆ operator()()

WDataSetScalar::SPtr WDataSetDTIToScalar_I::operator()	(	WProgress::SPtr	progress,
		WBoolFlag const &	shutdown,
		WDataSetDTI::SPtr	tensors,
		WDataSetVector::SPtr	evals
	)

virtual

This runs the given strategy on the given dataset.

Parameters

progress	the progress instance you should increment each time you fill the value for one voxel.
shutdown	Possibility to abort in case of shutdown.
tensors	The tensor components
evals	The Eigenvalues

Returns: The scalar dataset, for which each tensor a scalar value is derived according to the subclass implementation.
