Detailed Description

template<class TIndexValue = unsigned int, unsigned int VDimension = 3>
class itk::HilbertPath< TIndexValue, VDimension >

Represent an n-dimensional Hilbert path for a given order.

This class is used to construct a Hilbert spacing-filling curve (or path) for a given order and given dimension. The locality- preserving properties make the Hilbert path an attractive option for mapping multi-dimensional data to a single array.

The path is defined by its dimensionality and order( >= 1 ) with its starting point at [0]^Dimension. The size of the path in each dimension is 2^order where each discrete location is visited by that path. For example, a 2-D Hilbert path of order 8 can map each pixel of a 256x256 image onto a single array. More properties and visualizations can be found in various places on the web.

The implementation is based on Chris Hamilton, "Compact Hilbert Indices", Technical Report CS-2006-07, July 24, 2006. and a direct porting of the Aldo Cortesi's python code found at https://github.com/cortesi/scurve
