A three-stage framework to active source localization from a binaural head

Gabriel Bustamante, Alban Portello, Patrick Danès

Abstract

This paper takes place within the field of binaural localization in robotics. The aim is to design “active” schemes, which combine the signals sensed by a binaural head with its motor commands so as to overcome limitations occurring in a static context: front-back confusion, non-observability of hidden variables, etc. A three-stage strategy is proposed, which entails: the short-term detection and localization of sources from the short-term analysis of the binaural stream; the assimilation of these data over time and the fusion with the motor commands of the binaural sensor; the improvement of this fusion through the feedback control of the binaural sensor. For each stage, the theoretical bases, some achievements and open problems are outlined.
