MATLAB Implementation of a Box Particle Filter for tracking multiple extended objects An algorithm for tracking multiple extended objects is developed. The algorithm is a Box particle filter. The program is modular and self-contained. Code linked to the paper: "A Box Particle Filter Method for Tracking Multiple Extended Objects", doi: 10.1109/TAES.2018.2874147. The Box particle filter requires a library called Intlab for operation. This library can be purchased and downloaded from: http://www.ti3.tu-harburg.de/rump/intlab/
