ITK v5.0.rc01 Release Notes

Release Date: 2019-02-05 // about 5 years ago

  • πŸš€ We are happy to announce the Insight Toolkit (ITK) Release Candidate 1! πŸŽ‰ As the first release candidate, the major advancements for ITK 5 have matured, and the community is encouraged to adopt the release candidate in ITK-based applications.

    πŸš€ This release improves Mesh support in Python though simplification and extension of Mesh and PointSet wrapping. In general, this release makes improvements to the modernization of the toolkit staged in ITK 5.
    The C++ range classes continue to advance, including the experimental itk::ImageBufferRange, itk::IndexRange, and itk::ShapedImageNeighborhoodRange. Our migration to GitHub was overwhelmingly successful, but it continues to improve. Pull requests now receive a helpful CDash build analysis GitHub Check.

    πŸ— GitHub CDash Build Analysis Check

    πŸš€ For an overview of ITK 5's transition to modern C++, performance-related changes, the new, Pythonic API, and the project's migration to GitHub, see the ITK 5 Alpha 1: Modern C++, ITK 5 Alpha 2: Performance, ITK 5 Beta 1: Pythonic Interface, and ITK 5 Beta 3: GitHub release announcements.

    🐎 Performance Improvements

    • N4BiasFieldCorrectionImageFilter accelerated through itk::ImageBufferRange and other optimizations.
    • 🚚 Various modern C++ improvements related to default constructors, move operations, etc.

    πŸ“š Documentation

    • ⚑️ ITK Software Guide PDF is now updated for ITK 5.
    • TransformIndexToPhysicalPoint notation is improved.

    Infrastructure

    • πŸ‘ Mesh IO classes, e.g. Gifti, OBJ, OFF, FreeSurfer, BYU, STL, are now split into separate modules for better modularity.
    • πŸ— A CDash build analysis summary and link is provided as a GitHub Check.
    • βž• Added new C++11 member functions from std::vector to itk::VectorContainer.

    Third Party

    • πŸ‘ DCMTK 3.6.4 is now supported.
    • CanRead is now faster for inspection of potential DICOM files, both with the GDCM and DCMTK DICOM backends.
    • ⚑️ Eigen updated to 3.3.7.
    • πŸ‘Œ Improved support for integration of a system Eigen.
    • πŸ‘Œ Improved compatibility with system HDF5.

    Python

    • Wrapping for Mesh and PointSet classes was simplified and extended.
    • BinaryMaskToNarrowBandPointSetFilter is now available in Python.
    • πŸ‘ Better itk.Image NumPy buffer management for advanced pipeline grafting.

    πŸš€ To install the 5.0 Release Candidate 1 Python packages, run

    python -m pip install --upgrade pip python -m pip install --upgrade --pre itk

    What's Next

    πŸš€ There are many more bug fixes and improvements not mentioned above. For more details, please see the change log below. Congratulations and thank you to everyone who contributed to this release.

    πŸ“š The ITK 5 Migration Guide is available to help transition a code base from ITK 4 to ITK 5. Please discuss your experiences on Discourse.

    πŸš€ We are approaching the 5.0.0 final release! The next release will be the second ITK 5 release candidate; it is scheduled for March.

    Enjoy ITK!
