ITK 5.4 Release Candidate 1: C++17 We are happy to announce the Insight Toolkit (ITK) 5.4 Release Candidate 1 is available for testing! :tada: ITK is an open-source, cross-platform toolkit for N-dimensional scientific image processing, segmentation, and registration. :flashlight: Highlights ITK 5.4 is a feature release that continues our modern C++ evolution by requiring C++17. The toolkit progresses in performance with a simple and elegant style and syntax. Through hundreds of changes in this release, we advance in readability and maintainability for the library and client code, often facilitated by improvements in the C++ standards. Community contributions through Remote extension Modules are a valuable source of innovation in ITK, and updates to 30 modules in this release are no exception. A few examples of the Remote Modules updated include: BoneMorphometry, Cleaver, GenericLabelInterpolator, IOScanco, LabelErodeDilate, MinimalPathExtraction, Montage, MorphologicalContourInterpolation, ParabolicMorphology, RANSAC, ReconstructionToolkit (RTK), TextureFeatures, TubeTK, Ultrasound, VkFFTBackend, and WebAssemblyInterface. New modules can quickly be created with a cookiecutter and cross-platform testing for high quality development and Python package generation is supported by a reusable GitHub Action. For more information, see Chapter 9 of the ITK Software Guide. Highlights from the ITKElastix Remote Module presentation at SciPy 2023, the Annual Scientific Computing with Python Conference.
