    ITK on GitHub

    🍎 An important step has been taken to faciliate participation of the community in the development of ITK: The official repository was moved to GitHub! This move includes ITK's main repository, as well as many other ITK projects such as the ITKExamples, and many ITK remote modules. It is now very easy for anyone to participate in the development of the library. This has already been a success with many new authors getting involved and submitting patches through the GitHub pull-request mechanism. This change also includes moving the issue tracker to the GitHub issue tracker where any problem encountered with ITK should be reported. ITK's GitHub migration was explained in more detail in ITK 5.0 Beta 3: GitHub. Finally, moving ITK to GitHub made it straightforward to use Microsoft Azure Pipeline Continuous Integration platform: Each pull-request is tested on all 3 major platforms (Windows, Linux, MacOS) and Python builds can be requested to ensure that a patch can be integrated.

    C++11

    Major C++ code refactoring brought dramatic improvements to ITK's API and performance (see ITK 5.0 Alpha 1: Modern C++ for more details). ITK now uses the C++11 standard allowing the developers full access to its new powerful features such as range-based loops, constexpr, lambda expressions, and uniform initialization syntax. Using C++ 11 also removes the necessity of many ITK macros (e.g. ITK_NULLPTR, ITK_DELETED_FUNCTION) which have equivalents in the new standard. This also leads to changes in style to match the C++ 11 best practices. This includes replacing typedef calls with the using keyword to improve source code readability. ITK's C++ code is easier to read, understand, and maintain!

    Thread Pool

    πŸš€ This new release of ITK also integrates big performance improvements thanks to the refactoring of the multithreading infrastructure with a thread pool available by default, and the possible usage of the Intel Threading Building Blocks (TBB) threading backend (see ITK 5.0 Alpha 2: Performance for benchmarks).

    Spatial Objects

    βž• Additionally, a major upgrade of the ITK Spatial Object framework, which provides a representation of objects and the mechanism to specify their spatial relationship relative to other objects in a scene, was integrated in this new version of ITK. The new code improves consistency in the programming interface and simplifies implementation and usage (more details in ITK 5.0 Release Candidate 2: Spatial Object’s.

    πŸ†• New Features

    πŸš€ Other new features in this ITK release include new algorithms, better mesh support (see ITK 5.0 Release Candidate 1: Meshes), new global variable model using one singleton, and better streaming capabilities.

    Third Party Libraries

    ⚑️ Eigen, a C++ library for linear algebra, was integrated in ITK and gradual transition from VXL to Eigen for Linear algebra is planned. Many third party libraries were updated: VNL, DCMTK, GDCM, HDF5, KWSys, MetaIO, Zlib, GIFTI, nifti, pygccxml.

    Remote Modules

    πŸš€ Remote modules, which allow easy integration of new image processing algorithm in ITK, were updated and new Python packages compatible with this new release of ITK were created. Four new remote modules were also added to ITK: PhaseSymmetry, IOOpenSlide, Montage, and BSplineGradient (description of the modules in ITK 5.0 Beta 3: GitHub).

    Python

    πŸš€ Traditionally, ITK in Python had to be used through an object-oriented interface. In this new release, we have added a functional interface which is more Pythonic and should be more familiar to Python programmers. Examples on how to use this new procedural interface are available in ITK 5.0 Beta 1: Pythonic Interface.

    Congratulations

    πŸš€ Congratulations and thank you to everyone who contributed to this release. Of the 49 authors, we would like to specially recognize the new contributors, Isaiah Norton, maekclena, Rashad Kanavath, Bai Shi, Hui Xie, Martino Pilia, Ally Warner, pierre33, Chao Wu, Gregory C. Sharp, Bryce A Besler, Kwame Kutten, Mihail Isakov, Jerome Schmid, Roman Grothausmann, Alexis Girault, Gabriel A. Devenyi, Marian Klymov, Thomas Janvier, and Forrest Li.

    Migration to ITKv5

    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.

    What's Next

    Join us in the creation of advanced, open source scientific image analysis tools. Get started with the ITK examples. Take part in the community discussion at discourse.itk.org. Contribute with pull requests, code reviews, and issue discussions in our GitHub Organization.

    πŸš€ We have a soft commitment to backwards compatibility to address any potential API or architectual issues until the next feature release. Stay tuned for upcoming announcements on ITK's integration with modern web technologies and improved support for Remote Module development on GitHub.

    Enjoy ITK!

    Image denoising with the new ITKTotalVariation remote module. Left: Transmission electron microscopy image of pectin. Right: Denoised image.

    This release features a major upgrade to the ITK Spatial Object framework, led by Stephen Aylward, with contributions from Hastings Greer, Forrest Lee, Niels Dekker, Dženan Zukić, and Hans Johnson. In ITK, a itk::SpatialObject provides a representation of objects and the mechanism to specify their spatial relationship relative to other objects in a scene. Objects can be images but also abstract, parametric entities, such as a ellipse, box, or arrow, or point-based, such as a tube, contour, or surface. Objects can be organized into spatial hierarchies.SpatialObjects are key for model-based registration, integration of segmentation results in multiple formats, conversions to and from images, and capturing spatial relationships between structures.

    In ITK 5, the SpatialObject framework was refactored to improve consistency in the the programming interface and simplify implementation and usage. As a result, incorrect or unexpected behaviors are avoided. Complexity and dependency were reduced by removing a dependency on the VNL tree data structures. Additionally, IndexSpace was removed from the API of all SpatialObjects to prevent ambiguity while providing a consistent and intuitive interface. Only two reference spaces are consistently and explicitly available in the API: ObjectSpace and WorldSpace. ObjectSpace is the space local to each object, where the object's parameters are defined. WorldSpace is the coordinate system defined by the top-level SpatialObject in a hierachy, which is defined by parent-child object relationships. Only two transforms are now consistently and explicitly available in the API: ObjectToParent transform and ObjectToWorld transform. The ObjectToParent transform moves an object within its parent's ObjectSpace. The ObjectToWorld transform is derived from component ObjectToParent transforms and is provided for convenience and to reduce redundant computations. The API is now more explicit regarding the space that an operation applies to. For instance, IsInside(point) is now IsInsideInObjectSpace(point) or IsInsideInWorldSpace(point). For more information on the SpatialObjects changes, see the ITK 5 Migration Guide.

    πŸš€ The Python package synchronization infrastructure for static global variables was refactored to support more variables and permit future additions to the singleton. This will prevent the need to rebuild remote module binary Python packages following future releases of ITK 5. However, current remote module Python packages that use ITK 5 should be rebuilt and republished for ITK 5.0 RC 2.

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

  • v5.0.rc01

    February 05, 2019

    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!
