These are fully independent, compilable examples. There is significant overlap in the examples, but they are each intended to illustrate a different concept and be fully stand alone compilable.
{{warning|1=The media wiki content on this page is no longer maintained. The examples presented on the https://itk.org/Wiki/*  pages likely require ITK version 4.13 or earlier releases.   In many cases, the examples on this page no longer conform to the best practices for modern ITK versions.
Please add examples in your areas of expertise!
You can checkout the entire set of examples from this repository:

===ItkVtkGlue===
ITK and VTK are very separate toolkits - ITK for image processing and VTK for data visualization. It is often convenient to use the two together - namely, to display an ITK image on the screen. The ItkVtkGlue kit serves exactly this purpose. Also provided inside ItkVtkGlue is a QuickView class to allow a 2 line display of an ITK image.
 
If you download the entire ITK Wiki Examples Collection, the ItkVtkGlue directory will be included and configured. If you wish to just build a few examples, then you will need to [http://gitorious.org/itkwikiexamples/itkwikiexamples/blobs/raw/143b4a80c6f5bbe44edbcbeccaa9c05b83042d65/ItkVtkGlue.tar.gz download ItkVtkGlue] and build it.
