ITK Release 5.0 Release Candidiate 1¶
We are happy to announce the Insight Toolkit (ITK) Release Candidate 1! :tada: 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.
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.
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 throughitk::ImageBufferRange
and other optimizations.Various modern C++ improvements related to default constructors, move operations, etc.
Documentation¶
ITK Software Guide PDF is now updated for ITK 5.
TransformIndexToPhysicalPoint
notation is improved.
Infrastructure¶
Mesh IO classes, e.g. Gifti, OBJ, OFF, FreeSurfer, BYU, STL, are now split into separate modules for better modularity.
A CDash build analysis summary and link is provided as a GitHub Check.
Added new C++11 member functions from
std::vector
toitk::VectorContainer
.
Third Party¶
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.
Improved support for integration of a system Eigen.
Improved compatibility with system HDF5.
Python¶
Wrapping for
Mesh
andPointSet
classes was simplified and extended.BinaryMaskToNarrowBandPointSetFilter
is now available in Python.Better
itk.Image
NumPy buffer management for advanced pipeline grafting.
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¶
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.
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.
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!
