Developed by an international community, ITK collects best-of-breed algorithms for registering, segmenting, analyzing, and quantifying n-dimensional imaging data. The high-quality library facilitates reproducible research, provides a software resource for teaching image analysis, and offers a platform for commercial product development.

Here are a few selected highlights for this release:

  • ITK is on PyPI: install ITK’s Python wrapping with: pip install itk

  • IsotropicWavelets remote module: isotropic and steerable wavelets in the frequency domain

  • Improvement of the Image IO, including full 64 bit pixel support

  • ITK Python interface improvements: use ITK in a procedural way

  • Improved image and transform IO factory registration

  • ITK’s thread pool refactored for improved performance

  • Improved ITK test driver to compare images spacing, origin, size and direction

This release brings multiple exciting new developments for ITK’s Python wrapping.

Binary Python Packages Binary Python wheels are available for Linux, macOS, and Windows, for Python 2.7 and the recent Python 3.X. The wheels have been published on PyPI, the Python package index. These binary wheels are built to be compatible with Python distributions from, system package managers like apt and Homebrew, and Anaconda. (official announcement here). This means that it has never been easier to install and start using ITK: one simple pip install itk command, and a few seconds later it is possible to start interactively processing images.

External Module Python Packages Furthermore, Python packages for externally developed ITK modules can now be automatically generated and uploaded to PyPI. The module Python package is created by free GitHub continuous integration services. Like the main ITK packages, these packages embed documentation from Doxygen comments into Python docstrings. See for details on how to get started. A number of novel ITK module Python packages have already been created this way, including

  • itk-bonemorphometry

  • itk-polartransform

  • itk-texturefeatures

  • itk-anisotropicdiffusionlbr

  • itk-ultrasound

  • itk-morphologicalcontourinterpolation

  • itk-cuberille

  • itk-ringartifact

IsotropicWavelets Remote Module A Python package is available for a powerful new remote module, IsotropicWavelets. This module implements a multiresolution (MRA) analysis framework using isotropic and steerable wavelets in the frequency domain. This framework provides the backbone for state of the art filters for denoising, feature detection or phase analysis in N-dimensions. Since it is wrapped in Python, it is as easy to use as ITK: Install the module with pip install itk-isotropicwavelets. Write a Python script or start an interactive Python environment, and call import itk. All the functionality of IsotropicWavelets will be available.

Procedural Filter Interface for Rapid Prototyping ITK v4.13.0 also incorporates an API improvement throughout the entire toolkit to facilitate rapid prototyping: ITK Python filters are now callables, so ITK can be used in a procedural way. It is possible to run filters without the need to declare a filter object first, and without the need to explicitly call ‘Update()’ on a pipeline.

itk.imwrite(itk.MedianImageFilter(itk.imread(‘my_image.png’), Radius=4), ‘my_output.png’)

This one-liner will read an image, filter it with the MedianImageFilter with a radius of 4 voxels, and save the result in a different file.

Image IO Improvement, including Full 64 bit Pixel Support Several improvements have been made in the Image IO in this major release: 64 bit images are now consistently supported by all Image IOs. Additionally, MINC image IO is now enabled by default, Bruker IO improved and enabled by default, and DICOM support via DCMTK was greatly improved (and supported on MS Windows). See below “Improved Factory Registration” for the last improvement of Image IO in this release.

GoogleTest for Writing Tests An ITK module can be tested with GoogleTest library, using the CMake funtion CreateGoogleTestDriver(), in addition to the classic ITKTestDriver. This function will add the GTest dependency to your test. GoogleTest makes it easy to write a lot of different tests to verify that your code works. Examples of tests using this framework can be found in ITK in Modules/Filtering/ImageGrid/test/itkSliceImageFilterTest.cxx, /Modules/Filtering/ImageIntensity/test/itkArithmeticOpsFunctorsTest.cxx, and several other files.

Improved Factory Registration Each module (including remote modules) can list the factories and formats they support. This information is used to automatically register all formats supported by modules loaded during configuration. When loading ITK with the CMake command find_package() and loading a limited number of ITK components, it is now possible to load all modules corresponding to a factory, e.g. ImageIO, TransformIO. To load all components of a factory, add the component ITK<factory> in the list of requested components. Here is an example that finds ITK with the ITKCommon module and all the available image and transform IO modules:


ITK’s Thread Pool Refactored for Improved Performance ITK’s thread pool has been refactored for improved performance. To test the thread pool, set the environment variable:


Or, call the static method


at the start of your application. The thread pool is still experimental, and its implementation and interface will be improved and modified in the near future.

Improved ITK test driver to compare images spacing, origin, size and direction In part to support improved testing and support for DICOM image metadata, the ITK test driver now checks image spacing, origin, and direction when making baseline image comparisons. If your project uses the ITK test driver, new image baselines with correct metadata information may be required. Alternatively, pass the --ignoreInputInformation flag to the test driver.

Congratulations to the 26 contributors to this release. We would especially like to recognize the new contributors: Laura Pascal, Beatriz Paniagua, Rene-Paul Debroize, Edwin Bennink, David Kügler, Adrien Bailly, and Steve Pieper.

The next feature release, scheduled for June 2018, will be ITK 5.0. This release will introduce thread pools by default with an optional Intel Threading Building Blocks (TBB) backend, require C++11 compiler support, and require a newer version of CMake.
