Title: Level Set Segmentation: Active Contours without edge
Author(s):mosaliganti k., smith b., gelas a., gouaillard a., megason s.
Abstract: 
An Insight Toolkit (ITK) processing framework for segmentation using active contours without edges 
is presented in this paper. Our algorithm is based on the work of Chan and Vese [1] that uses level- 
sets to accomplish region segmentation in images with poor or no gradient information. The basic idea 
is to partion the image into two piecewise constant intensity regions. This work is in contrast to the 
level-set methods currently available in ITK which necessarily require gradient information. Similar to 
those methods, the methods presented in this paper are also made efficient using a sparse implementation 
strategy that solves the contour evolution PDE at the level-set boundary. The framework consists of 6 
new ITK filters that inherit in succession from itk::SegmentationFilter. We include 2D/3D example 
code, parameter settings and show the results generated on a 2D cardiac image.
