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. Please add examples in your areas of expertise!

Simple Operations

Example Name ITK Classes Demonstrated Description
Distance between two points Point
Create a vector Vector
Create a covariant vector CovariantVector
Variable length vector VariableLengthVector main() works properly, but neither conversion seems to work.

Working with Images

Example Name ITK Classes Demonstrated Description
Apply a custom operation to each pixel in an image UnaryFunctorImageFilter
Find the minimum and maximum value (and the position of the value) in an image MinimumMaximumImageCalculator
Add two images together AddImageFilter
Paste a part of one image into another image PasteImageFilter
Flip an image over specified axes FlipImageFilter The axes specification is not quite right - warning: address of axes always evaluates true
Create a vector image VectorImage An image with an ND vector at each pixel
Multiply two images together MultiplyImageFilter
Extract the boundaries of connected regions in a binary image BinaryContourImageFilter
Iterate over a region of an image with a neighborhood NeighborhoodIterator
Iterate over a region of an image ImageRegionIterator
Read an image ImageFileReader
Extract a portion of an image (region of interest) RegionOfInterestImageFilter
Write an image ImageFileWriter
Compute the gradient magnitude image GradientMagnitudeImageFilter
Smooth an image using curvature flow CurvatureFlowImageFilterType
Rescale the intensity values of an image to a specified range RescaleIntensityImageFilter
Set specified pixels to specified values Image

Missing

Example Name ITK Classes Demonstrated Description
Switch the axes of an image PermuteAxesImageFilter
Crop an image CropImageFilter Works, but I'm not exactly sure how to specify the crop region. The documentation should be improved.
Pad an image with a constant value ConstantPadImageFilter Not sure how to specify the final output size/extent. The documentation should be improved.
Pad an image MirrorPadImageFilter Not sure how to specify the final output size/extent. The documentation should be improved.
Pad an image by wrapping WrapPadImageFilter Not sure how to specify the final output size/extent. The documentation should be improved.
Shrink an image ShrinkImageFilter Image doesn't seem to be shrunk?

Broken

Example Name ITK Classes Demonstrated Description
