Given a domain defined by lower and upper bound points and
requested_number_of_splits implements two functions:

  • computeSplits returns the number of splits that the
    region can hold (lesser or equal than the requested)
  • getSplit returns the ith split and the outputLowerBound and
    outputUpperBound of the split region.

Implementation acquired from ITK: itkImageRegionSplitterMultidimensional.cxx
https://github.com/InsightSoftwareConsortium/ITK/blob/f971477cdacff22a861dfcbaccd89c0cf2755af7/Modules/Core/Common/src/itkImageRegionSplitterMultidimensional.cxx

  • Add splitComplex to SplitFunctions
  • Add test and change testSplitFunctions to use Catch

Checklist

  • Unit-test of your feature with Catch.
  • Doxygen documentation of the code completed (classes, methods, types, members...)
  • [NA] Documentation module page added or updated.
  • New entry in the ChangeLog.md added.
  • No warning raised in Debug cmake mode (otherwise, Travis C.I. will fail).
  • All continuous integration tests pass (Travis & appveyor)

This is a rebase from #1448. The thinning algorithm with splits was discarded.

Given a domain defined by lower and upper bound points and
requested_number_of_splits implements two functions:
- computeSplits returns the number of splits that the
region can hold (lesser or equal than the requested)
- getSplit returns the ith split and the outputLowerBound and
