Simultaneous Tracking of Multiple Objects Using Fast Level Set-Like Algorithm

Martin Maska, Pavel Matula & Michal Kozubek
A topological flexibility of implicit active contours is of great benefit, since it allows simultaneous detection of several objects without any a priori knowledge about their number and shapes. However, in tracking applications it is often required to keep desired objects mutually separated as well as allow each object to evolve itself, i.e., different objects cannot be merged together, but each object can split into several regions that can be merged again later in time....
