<h3>Objective</h3>
Develop a general purpose active contour segmentor in Slicer3.

More detail and testing are at [[RobustStatisticsSegmentation|here.]]

</div>

<div style="width: 27%; float: left; padding-right: 3%;">

<h3>Approach, Plan</h3>
Driven by the robust statistics, we provide an active contour segmentor module for general purpose in Sclier3. The algorithm will simultaneously extract multiple objects in the scene given some user provided labels.

'''Plan for project week:''' Integrated into Slicer3 using interactive module.

</div>

<div style="width: 40%; float: left;">

<h3>Progress</h3>
The CLI is already on Extension server and ready to be used through extension manager in Slicer.

The next step is to change the user input manner from fiducial points to label maps.

Furthermore, we plan to use multiple labels to simultaneously extract multiple objects.
