ITK 4.6.0 has been released!

On behalf of the Insight Toolkit community, we are proud to announce that ITK 4.6.0 has been released!

 

Links to the Sourceforge.net tarballs can be found on the download page.

 

The 4.6 release is a major milestone that marks the hard work of many outstanding community members.

Among the major contributions in this release are improved Remote Module support with a number of exciting new Remote Modules.  The TransformToDisplacementField filter and a entire module of image noise generation classes were migrated into the default build. A number of new optimizers were added to the Registrationv4 framework, which also experienced a number of performance improvements. Performance improvements were a general theme as was improved code coverage. Python wrapping underwent a huge cleanup.

Our documentation continues to improve with better examples, Doxygen documentation, and guidance material.  The Software Guide was split in anticipation of the release of two new hard copy books.

Thanks to everyone for their hard work!

Enjoy ITK!

 

 

New Documentation

Our documentation continues to improve.  Remote modules are now grouped in the Doxygen Module page. A number of new examples were added to the Sphinx repository and the Wiki, which can now also be built as Remote modules. The Software Guide was split into two books and ITK configure and build instructions were revised.
