[Insight-users] itk2DEdgeDetectionSample

[Joshua Cates]

Hello Mathieu,

This example is old and needs some updating.  The build configuration
should be modified as well.  We'll have a look at it and make sure it
compiles properly and also update the I/O.  Thanks for bringing it to our
attention.

Josh.
