It was extended to file formats to support a variety of objects that occur in medicine such a tubes (for vessels, needles, etc.), blobs (for arbitrary shaped objects), cubes, spheres, etc. The complete library is known as MetaIO |
| Module ITKNIFTI | This module contains the third party NIFTI library. Neuroimaging Informatics Technology Initiative provides an Analyze-style MRI file format |
| Module ITKNetlib | This module contains the third party netlib slatec routines. They are used by the probability distributions in ITK |
| Module ITKNrrdIO | This module contains the third party NRRD image file format |
| Module ITKOpenJPEG | This module contains the third party OpenJPEG library. The OpenJPEG library is an open-source JPEG 2000 codec written in C language. It has been developed in order to promote the use of JPEG 2000, the new still-image compression standard from the Joint Photographic Experts Group (JPEG) |
| Module ITKPNG | This module contains the third party Portable Network Graphics (PNG) image file format library |
| Module ITKTBB | |
| Module ITKTIFF | This module contains the third party Tag Image File Format (TIFF) image file format library |
| Module ITKVNL | This module contains the third party VNL numeric library from the VXL vision library suite |
| Module ITKVNLInstantiation | This module contains instantiated templates of basic data types found in the VNL third party module |
| Module ITKZLIB | This module contains the third party zlib-ng general purpose data compression library, designed as a drop-in replacement for ZLIB |
| Module ITKLIBLBFGS | This module contains the third party libLBFGS library, a C++ implementaiton of the LBFGS implementation in Netlib |
| ►Group Bridge | This group of modules are intended to bridge ITK to other toolkits as libraries such as visualization toolkits |
| Module ITKBridgeNumPy | |
| Module ITKVTK | This module contains classes intended to interconnect ITK and VTK (The Visualization Toolkit). It is common to combine these two toolkits for the purpose of integrating in a single application the image analysis functionalities of ITK with the visualization functionalities of VTK. In particular, you will find here the classes that enable you to convert an itkImage into an vtkImageData, and to convert a vtkImageData into an itk::Image, all without having to duplicate their buffers |
| Module ITKVtkGlue | This module contains classes that provide an interface between ITK and VTK |
| ►Group Nonunit | This group of modules are intended to make use of an extensive set of the toolkit modules |
| Module ITKIntegratedTest | This modules contains tests targeting the behavior of multiple modules of the toolkit when they act together |
| Module ITKReview | These classes came into the toolkit from the Insight Journal and are staged to be integrated into the appropriate Module if they are high quality and see high use. If they are low quality or serve a very specific use case, they may be removed or made available as an ExternalModule |
| ►Group Compatibility | This group contains modules that ease the transition to ITKv4 and Deprecated classes |
| Module ITKDeprecated | |
| ►Group Remote | This group of modules is for ITK based code that have additional third-party dependencies not bundled with the toolkit, new algorithms or implementations seeking greater exposure and adoption, algorithms that hope to eventually be integrated into the toolkit, niche algorithms with limited application, and Modules in progress that do not yet have the test coverage and cross-platform standards required by the main toolkit. The modules are OFF by default in ITK's CMake configuration. Note that these modules do get the same level of support and backwards compatibility as other modules in the toolkit |
| Module AnalyzeObjectLabelMap | |
| Module AnisotropicDiffusionLBR | |
| Module Cuberille | This module implements cuberille implicit surface polygonization for ITK. This method operates by diving the surface into a number of small cubes called cuberilles. Each cuberille is centered at a pixel lying on the iso-surface and then quadrilaterals are generated for each face. The original approach is improved by projecting the vertices of each cuberille onto the implicit surface, smoothing the typical block-like resultant mesh |
| Module FixedPointInverseDisplacementField | FixedPointInverseDisplacementField takes a displacement field as input and computes the displacement field that is its inverse. If the input displacement field was mapping coordinates from a space A into a space B, the output of this filter will map coordinates from the space B into the space A |
| Module HigherOrderAccurateGradient | This module contains a filter to compute higher order accurate numerical derivatives and gradients from an input scalar image. Higher Order Accurate Derivative and Gradient Calculation in ITK https://www.insight-journal.org/browse/publication/775 https://hdl.handle.net/10380/3231 |
| Module MGHIO | This modules contains an ImageIO class to read or write the MGH file format that is an integral part of FreeSurfer based tools |
| Module MinimalPathExtraction | |
| Module MorphologicalContourInterpolation | The modules provides filters to do interpolation of manually segmented anatomical contours. Enabling testing requires RLEImage module to be enabled |
| Module MultipleImageIterator | Several applications such as multi-atlas segmentation require frequent iteration over multiple image volumes at the same time. Doing so with the regular ITK iterators is tedious and error prone as it requires updating each iterator at end of each iteration. Failing to do so results in hard to debug errors and crashes. The MultipleImageIterator is a simple wrapper class that tries to make this more convenient |
| Module PrincipalComponentsAnalysis | This module contains an implementation of the principal component analysis for the ITK toolkit |
