[vtkusers] Find Edge between Two Points

[Ken Urish]

Katya

ITK is excellent for this. Yes, its a new librarary, but it will do
what you want perfectly.

You need to implement a path framework. Given a series of points
manually selected by the user, the path framwork will create a
chain-code segmentation.

In itk:

Please refer to the Inisght Journal article -
http://insight-journal.org/browse/publication/38

I believe the insight journal article has supporting examples as well.

Thanks
