Fuzzy Neural Control Systems — Explained

Neural networks and fuzzy logic can conquer control-system challenges that leave conventional systems helpless. Here’s how they work, and how they benefit applications like high-speed image processing.

Abstract
We apply a multi-target recursive Bayes filter, the probability hypothesis density (PHD) filter, to a visual tracking problem: tracking a variable number of human groups in video. First, we use background subtraction to detect human groups which appear as foreground blobs. The PHD filter is implemented using sequential Monte Carlo methods; and the centroids of the foreground blobs are used as the measurements to update the PHD filter. Our experimental results show that when human groups appear, merge, split, and disappear in the field of view of a camera, our method can track them correctly. Link

Cooperative Exploration Simulation

Simulates cooperative exploration using 1..n robots. The robots can work independently or employ cooperative localisation where they estimate eachothers' pose. These options are set by the arguements passed to the constructor for the class Simulation.
The robots can employ one or more behaviours, which they switch between based on their potential utility. These can be included/excluded by setting the appropriate flags in the constructor for the class BehaviourData.
The simulation currently works on a single computer with communication between robots and board simulated using shared memory. Will soon be extended to allow execution on different machines with communication via sockets, and eventually over bluetooth.
