This paper introduces data fusion strategies within particle filtering in order to track people from a single camera mounted on a mobile robot in a human environment. Various visual cues are described, relying on color, shape or motion, together with several filtering strategies taking into account all or parts of these measurements in their importance and/or measurement functions. A preliminary evaluation enables the selection of the most meaningful visual cues associations in terms of discriminative power, robustness to artifacts and time consumption.
