[Insight-users] Contour extracton algorithm for binaty pixels

[Zachary Pincus]

I wrote such a filter to fill this need in ITK several months ago. It  
currently resides, along  with many other useful filters, on the  
InsightJournal.

It applies a classic contour-extraction method (the 2d equivalent of  
marching cubes) to an image and gives back a set of  
itk::PolyLineParametricPath objects. To get contours from a binary  
image, you should set the contour value parameter to halfway between  
the inside and outside intensity.
