Multimodal identity tracking in a smartroom

Bernardin, K.; Ekenel, H. K.; Stiefelhagen, R.

Abstract. The automatic detection, tracking, and identification of
multiple people in intelligent environments is an important building
block on which smart interaction systems can be designed. Those could
be, e.g. gesture recognizers, head pose estimators or far field speech recognizers
and dialog systems.
In this paper, we present a system which is capable of tracking multiple
people in a smartroom environment while infering their identities
in a completely automatic and unobtrusive way. It relies on a set of
fixed and active cameras to track the users and get closeups of their
faces for identification, and on several microphone arrays to determine
active speakers and steer the attention of the system. Information coming
asynchronously from several sources, such as position updates from
audio or visual trackers and identification events from identification
modules, is fused at higher level to gradually refine the room�s situation
model. The system has been trained on a small set of users and showed
good performance at acquiring and keeping their identities in a smart
room environment.
