Detailed Description

template<typename T>
class carto::LightResampler< T >

Light, simple resampler used for flipping operations.

Contrarily to Resampler classes in aimsalgo, no interpolation is done, neither in space nor in values. We take the nearest voxel, report its value in the output. This also ensures the conservation of values in flipping operations.
