 <h3>Approach, Plan</h3>
-The current approach description.
+Currently we use a particle-filter tracking approach for segmenting the nerves. The algorithm is given a seed point, preferably somewhere in the spine. The particles are tubes following Bézier curves (and hence forming a B-spline track). To compute the likelihood of each sample we are experimenting with measures that use image intensity and gradients within the patch. Correct partial volume estimates are important in the measure as well.
-Plan for project week description.
