Abstract :
We present a novel resampling technique for particle filtering algorithms based on a model of attractive and repulsive forces. The new approach avoids the common degeneracy problem found in traditional resampling algorithms that prevents precise tracking of a source. The algorithm is applied to an 8 microphone source localization problem and is shown to accurately localize a single speaker
