Title: Live-Wire-ing the Insight Toolkit with Intelligent Scissors
Author(s): Tustison, Nicholas; Yushkevich, Paul; Gee, James
Abstract: 
Semi-automatic image segmentation algorithms depend on interaction with the user to accurately define a region of interest within an image.  Once such method is a dynamic programming approach called {em Intelligent Scissors} developed by Mortenson and Barret cite{Mortensen1992,Mortensen1995,Barrett1996,Barrett1997}.  Standard interaction involves the user-placement of a seed point on or near the boundary of the object to be extracted.  Using a gradient-based cost function, a {em live-wire} image path from the seed point to a subsequently placed boundary point is determined.  As this free point is manipulated with the mouse cursor, the live-wire boundary, which extends from the seed point to the varying free point, locks onto nearby edges within the image.  Although some applications do not require such user-interaction (e.g. cite{Hu2001}) warranting inclusion within the toolkit, incorporating live-wire capabilities into ITK-SNAP cite{Yushkevich2006} has been discussed and, th
 erefore, we would like to, as a preliminary step, vet the code within the ITK community.
