COBWEBS – Now in 3D!

Posted on

In a recent Proceeding of the SPIE, Stacey demonstrated an extension of COBWEBS (Combined Online Bayesian Windowed Estimation of Background and Signal) to the third dimension. In simulated trajectories, this 3D variant of COBWEBS enables continuous tracking of freely diffusing objects in heterogeneous environments with background levels several fold larger than the actual signal. The extension to 3D is an important step towards an experimental implementation of COBWEBS, which will dramatically expand the scope of what is possible with active-feedback tracking.
