Detailed Description

template<class TInputImage, typename TScalarType = double>
class itk::HighResLaplacianSolverImageFilter< TInputImage, TScalarType >

Solves Laplace equation over the cortical volume, but can be run at very high resolution, by setting the VoxelMultiplicationFactor to determine an effective voxel size.

So, if you set a VoxelMultiplicationFactor to 3, you have 3 times as many voxels in each dimension, and hence 1/3 the voxel dimension in each dimension.

The output is an image of voltage potentials, of the same size as the input. In addition, we expose the internal list of pixels used in the high resolution computations, so that subsequent pipeline steps can have access to them.
