Track Label and Classical and Quantum Probability Densities

Abstract

We discuss if track labels are needed in a tracker using physics-based reasoning. Using the concept of de Broglie wavelength, we show that it is possible to label macroscopic objects and their trajectories, whereas it is not possible to assign labels to microscopic objects. A number of cases are examined to show the difficulty of not using track labels in multitarget tracking. We analyze a simple case of two identical macroscopic and microscopic objects to show that indistinguishable macroscopic objects do not exist. Use of track labels in real-time and tracker evaluation is also discussed.
