ITK Release 4.3
===============

The Insight Software Consortium is happy to announce the release of ITK
4.3.0!

The 4.3.0 release is a major milestone that marks the hard work on many
outstanding community members.

We are excited to announce that experimental DICOM image reading is
available via the DCMTK library as a backend in addition to the GDCM
library. By default, DCMTK ImageIO support is not enabled. To try DCMTK
ImageIO support, turn the CMake option Module\_ITKIODCMTK ON. For Unix
platforms, the supporting DCMTK library will automatically be built as a
CMake ExternalProject. On Windows, the DCMTK library must be built
independently of the ITK build system. Then, specify the location to the
external build after setting the CMake option ITK\_USE\_SYSTEM\_DCMTK
ON.

WrapITK has undergone extensive improvements and bug fixes.

A number of registration-related feature enhancements were added. The
image registration methods have been updated to accommodate multiple
image metrics within a single optimization scheme. This permits, for
example, registration of a T1/T2 fixed image pair with a T1/T2 moving
image pair using a single metric for both T1 and T2 gradients or even
using two different metrics. New exponential transforms are available
along with automated B-Spline transform scale estimation. A new
physics-based non-rigid registration class is also available.

Updated third-party library versions include:

-   NrrdIO from Teem 1.11,
-   libtiff 4.03,
-   FFTW 3.3.2

A large number of important bugs were crushed, including fixes to the
ObjectFactoryBase, Patch-Based Denoising improvements, support for a
system libtiff, mesh processing, and FFTW use.

Support for itk::VectorImage’s was added to many algorithms, and a
single templated Adaptor class can now be applied without modification
to both itk::VectorImage’s and itk::Image’s of itk::Vector’s,
itk::RGBPixel’s, etc.

An extensive amount of code cruft was removed and coding style was made
more consistent; ITK gets more stylish and classy with every release!

Performance optimizations were achieved by removing GetInput/GetOutput
calls within filter inner loops, improving memory alignment, memory
access pattern optimizations, and parallelization through threading.

NOTE: As previously scheduled, Visual Studio 2005 will no longer be
supported after this release.
