Hi -

The National Library of Medicine Insight Segmentation and Registration Toolkit (ITK) is available for public download (this is an initial beta release). ITK is open-source like VTK, and is currently under active development. Go to http://www.itk.org for more information. Download the software at http://www.itk.org/HTML/Download.php. Some additional information is included at the end of this email.
Since ITK is relatively young, expect some rough edges. Any feedback that you can provide to the ITK developer community at this point in time is extremely valuable. There is a user mailing list available at



Welcome to the Insight Registration and Segmentation Toolkit (ITK)
This is the first public (beta) release of ITK. The ITK developer
community appreciates any feedback that you may have regarding
this software. Join the ITK user mailing list (instructions later)
and post your feedback there. Warning: since the software is young,
and this is a beta release, the API to the software will likely change
in the future.
Here are suggested steps for the ITK beginner. Please refer to
http://www.itk.org for more information.

1) Get the software. We strongly suggest that you obtain the pre-packaged
source code distributions (binaries/executables are not yet available).
+ http://www.itk.org/HTML/Download.php
You may also obtain CVS access. (This requires the CVS executable and
access to ITK's source code through your repository.) To check out the ITK
beta, use the following procedure:
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight login
(respond with password "insight")
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight co \
-r release-0_5-beta-branch Insight
The current development version of ITK is available using the
following process. Please realize that the development version is
inherently less stable than the beta release. If you access the
development version, you will want to monitor code quality at the
ITK Dashboard http://public.kitware.com/dashboard.php?name=itk.
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight login
(respond with password "insight")
cvs -d :pserver:anonymous@www.itk.org:/cvsroot/Insight co Insight

2) The software is compiled using CMake http://www.cmake.org. CMake
generates Makefiles on Unix platforms, and Windows workspaces (or
appropriate) build files according to your compiler, operating
system, and other system variables.
If at all possible, obtain the pre-compiled CMake binaries. Binaries
for Windows and various Unix flavors are available from
http://www.cmake.org/CMake/HTML/Download.html. On Windows, run the
CMSetup.exe to install CMake. On Unix, uncompress and untar the
package and place the executable in a location in your path.
On Windows, run CMake by clicking on CMakeSetup.exe. You have to point
CMake to the source directory (e.g., Insight), a build directory (where
the binaries and object files go), and choose the compiler. The GUI allows
you to choose build options and configure the build. Rerun CMake (by
selecting "Configure") until all "red" entries disappear. Then select
"Ok". This will produce a compiler workspace in the directory that you
On Unix, run "ccmake". This simple, curses-based GUI to CMake allows
you to configure the build process. First create a build directory
in which to generate object code and executables. Cd into this
directory and specify your C and C++ compilers with the environment
setenv CC your-c-compiler
setenv CXX your-c++-compiler
Next invoke "ccmake ../Insight" assuming that your build
directory is a sibling directory to Insight/. While running
ccmake, changes are made using the arrow keys to move over an
option, and the "Enter" key to edit it. Type "C" to configure
the build. As long as "*" appear next to any entries, keep
running CMake until none exist. Then type "G" to generate
makefiles and exit. Then run "make" in the build directory.
If you have difficulty with CMake, please refer to http://www.cmake.org
for additional instructions. It is possible to obtain CVS access and
compile CMake if absolutely necessary.

3) Join the mailing list. Go to
http://www.itk.org/mailman/listinfo/insight-users and follow the
instructions there. You may choose to receive a digest version of the
mail to minimize traffic.

4) Learn the system. Start by looking at the examples in
http://www.itk.org/HTML/Examples.htm. The source code is found in the
Insight/Examples source code directory. (To build the examples, make sure
the CMake flag "BUILD_EXAMPLES" is on.) You may also wish to peruse the
many tests found in Insight/Testing/Code.
