Brief Description

In this research, we employed deformable models to extract the surface contours in 3D medical images. By a first order estimation of local surface normals, we regroup the surface points into Monge patches that allow us to compute analytical surface models everywhere using a variant of the Facet Model. We can then characterize the brain surface in terms of 3D curvature patches that help to identify critical brain surface regions.
