Overview

Welcome to the National Library of Medicine Insight Segmentation and Registration Toolkit (ITK). ITK is an open-source, cross-platform system that provides developers with an extensive suite of software tools for image analysis. Among them, SimpleITK is a simplified layer built on top of ITK, intended to facilitate its use in rapid prototyping, education, interpreted languages. SimpleITK has the following main characteristics:

C++ library with wrappers for Python, Java, CSharp, R, Tcl and Ruby
Object-oriented
Provides a simplified, easy-to-use, procedural interface without templates
Is distributed under an open source Apache 2.0 License
Binary distributions for Python, Java and CSharp

SimpleITK captures many of features available in ITK, and is under ongoing development. Earlier in the development process a set of Specific Goals were outlined.

SimpleITK Notebooks

The SimpleITK Notebooks are examples and tutorials on how to use SimpleITK utilizing Jupyter Notebooks. This approach allows the user to create, edit and re-run scripts and view the results all within a web interface. The authoritative description of what Jupyter Notebooks are can be found on the Jupyter website. While SimpleITK supports a number of programming languages, the majority of notebooks are written in Python and some in R.

The main notebook repository is available on github.

Additional repositories containing tutorial specific notebooks are listed in the Tutorials section below.

Support

SimpleITK is supported through the ITK community and the active developers. In addition to the resources listed above in the documentation section, the discourse forum can be used to ask questions and obtain additional help from the ITK community. The legacy ITK mailing lists is no longer prefered.

Issue Tracking And Feature Requests

We are currently using the github issue tracker. Before switching to github issue tracking we used an instance of the Legacy Jira Issue Tracker hosted by the University of Iowa.

Releases

Development

SimpleITK has moved to a Github based work flow for issues tracking and contribution.

SimpleITK utilizes an additional "next" branch to merge and test changes before merging into the master branch. This makes our "master" branch more stable and reliable. This follows the CMake development process:

CMake Development Process

Source Code Repository

SimpleITK uses git as the revision control system. The official repository is hosted along side ITK as http://itk.org/SimpleITK.git [1]. It is also mirrored on Github .

Development is currently following the branchy workflow with the Kitware stage repository. This workflow is described here:

Contributions from github will be pushed to the stage repo and merged into the next branch by a SimpleITK developer.
