Release Notes

This page captures release notes for the intermediate releases of ITKv4

ITK 3-20 Git

This release is simply a Git tag that is equivalent to the stable release of ITK 3.2

ITKv4 Alphas

ITKv4 Alpha-01

The main changes made in this release are

Removal support for Deprecated Compilers

Code that was intended to provide support for several outdated compilers was removed. The compilers that are no longer supported in ITKv4 are

  • Borland 5.5
  • Visual Studio 6.0
  • Visual Studio 7.0
  • SGI CC compilers
  • Sun CC 5.6
  • Metrowerks


Note: The minimum version of the Sun CC complier that is supported is Version 12 as described in http://public.kitware.com/Bug/view.php?id=11076

Statistics Framework Updated

The original statistics framework was removed and replaced with the one that was refactored in 2007.

Details on the refactoring process are available at

Refactoring Statistics Framework 2007

and a guide on how to migrate to the new framework is available at

Migration Users Guide

Consolidated Morphology

The Consolidated Morphology classes that were in the ITK/Code/Review directory were moved into the standard ITK directories.

These classes were contributed in the Insight Journal paper


Multi-Threaded Image Registration Metrics Updated

The multi-threaded image registration metrics that were in the Review directory were moved into the standard ITK directories.

Details about the features of these metrics are available at 

 http://www.na-mic.org/Wiki/index.php/ITK_Registration_Optimization

and has been described in the Insight Journal paper 

 "Optimizing ITK’s Registration Methods for Multi-processor, Shared-Memory Systems"
 http://hdl.handle.net/1926/566
 http://www.insight-journal.org/browse/publication/172

With this change, the metric

  • Mean Squares
  • Mattes Mutual Information

will now use the number of threads that you assign them. This will be, by default, equal to the number of cores in your computer.

Centered Pixel Consistency Enforced

  • The changes that were made to enforce the consistency of pixel coordinates computation are now permanent.
  • The code intended for backward compatibility (with the state in which ITK was computing coordinates inconsistently) has been removed.

Remove all Deprecated code

  • Source code that was labeled as deprecated was removed.

Some CMake Options Removed

The following CMake configuration options were removed

  • ITK_USE_REVIEW_STATISTICS
  • ITK_USE_OPTIMIZED_REGISTRATION_METHODS
  • ITK_USE_CONSOLIDATED_MORPHOLOGY
  • ITK_USE_DEPRECATED_LEVELSET_INTERPOLATION
  • ITK_USE_CENTERED_PIXEL_COORDINATES_CONSISTENTLY
  • ITK_USE_DEPRECATED_FAST_MARCHING

ITKv4 Alpha-02

Adopted Uncrusty

The source code was processed using Uncrustify in order to reformat the coding style according to the following proposal
