Statistical Segmentation Slicer 2

Back to NA-MIC_Collaborations

Objective

We want to add various statistical measures into our PDE flows for medical imaging. This will allow the incorporation of global image information into the locally defined PDE frameowrk.

Progress

We developped flows which can separate the distributions inside and outside the evolving contour, and we have also been including shape information in the flows.

Completed

• A statistically based flow for image segmentation, using Fast Marching

• The code has been integrated into the Slicer
• A user-oriented tutorial for the Fast Marching algorithm is available at:Slicer Module Tutorial
