#include <itkImageHelper.h>
Fast Index/Offset computation.
These helper methods use recursive templates to unroll the loops of simple calculations. The resulting speed improvement varies from compiler to compiler. Some gcc compilers with debug turned on exhibit slight speed increases, but most compilers see improvement. The ComputeOffset performance improvement is impressive. For example, the Windows VS7.0 compiler shows almost a factor of 2 speed improvement with the recursive templates. Usually recursive templates use partial specialization to terminate loops. Here we use a technique used by Brad King in the itk Concept Checking code.
