Insight Segmentation and Registration Toolkit - Technical Summary

Technical Summary

The following sections summarize the technical features of the NLM's Insight ITK toolkit. Design Philosophy The following are key features of the toolkit design philosophy.

  • The toolkit provides data representation and algorithms for performing segmentation and registration. The focus is on medical applications; although the toolkit is capable of processing other data types.
  • The toolkit provides data representations in general form for images (arbitrary dimension) and (unstructured) meshes.
  • The toolkit does not address visualization or graphical user interface. These are left to other toolkits (such as VTK, VisPack, 3DViewnix, MetaImage, etc.)
  • The toolkit provides minimal tools for file interface. Again, this is left to other toolkits/libraries to provide.
  • Multi-threaded (shared memory) parallel processing is supported.
  • The development of the toolkit is based on principles of extreme programming. That is, design, implementation, and testing is performed in a rapid, iterative process. Testing forms the core of this process. In Insight, testing is performed continuously as files are checked in, and every night across multiple platforms and compilers. The ITK testing dashboard, where testing results are posted, is central to this process.

Famous quotes containing the words technical and/or summary:

    “The best work of artists in any age is the work of innocence liberated by technical knowledge. The laboratory experiments that led to the theory of pure color equipped the impressionists to paint nature as if it had only just been created.”
    —Nancy Hale (b. 1908)

    “I have simplified my politics into an utter detestation of all existing governments; and, as it is the shortest and most agreeable and summary feeling imaginable, the first moment of an universal republic would convert me into an advocate for single and uncontradicted despotism. The fact is, riches are power, and poverty is slavery all over the earth, and one sort of establishment is no better, nor worse, for a people than another.”
    —George Gordon Noel Byron (1788–1824)
