Motion classification for interpreting subcellular dynamics

Participants : Antoine Basset, Patrick Bouthemy, Charles Kervrann.

We have just started to address the classification of motions of subcellular particles in light microscopy time-lapse image sequences. For the while, we are considering the following three general classes: diffused motion, obstructed motion and directed motion. We are investigating three approaches. First, we can design likelihood ratio tests for deciding the relevant configuration on local patches. Second, we can define a short-term classification framework based on optical flow computed at time $t$. The third approach is a mid-term one exploiting pieces of trajectories (tracklets) computed by tracking a set of points.
