A few of the Insight Journal articles included as Remote Modules: LabelErodeDilate and MinimalPathExtraction

 

A few selected highlights for this release:

 

  • New remote modules: BridgeNumPy, LabelErodeDilate, ParabolicMorphology, MinimalPathExtraction

  • itk::FFTPadImageFilter to automatically pad images for the FFT implementation’s supported greatest prime factor

  • Additional point set registration capabilities.

  • More modules can be built as shared libraries.

  • GDCM, MetaIO, KWSys, MINC have been updated to their latest upstream versions.

  • Python wrapping is in excellent shape and works with the latest GCC, Clang, and MSVC.

  • Experimental cross-compilation support for Windows (MinGW-w64), ARMv6 (Raspberry Pi), ARMv7 (Android), ppc64le (POWER8), and JavaScript (Emscripten).

 



Please test the release candidate and share your experiences on the mailing list, issue tracker, and Gerrit Code Review. Since GDCM has seen a major upgrade to the latest version, please exercise DICOM IO, and be on the lookout for regressions.

 

An Experimental build, which demonstrates how the test suite performs on your local build system, can be submitted to the dashboard with:

 

 mkdir ../ITK-build

 cd ../ITK-build

 cmake ../ITK

 ctest -j 4 -M Experimental  -T Configure -T Build -T Test -T Submit


 

Visual Studio builds must also add “-C Release” to the ctest command.



Notify the mailing list if there are any unexpected failures.  Testing your own applications against the RC is also appreciated.

 

Congratulations and well done to the 31 contributors to this release. We would especially like to recognize the new contributors, David Froger, Cyril Mory, Dzenan Zukic, Ivan Setiawan, Jan Bergmeier, Rolf Eike Beer, Davis Vigneault, Gary JIA, and Alexander Hewer.

 



The final release will be approximately one week from now.
