— In this paper, we describe a robotic wheelchair system as guide robot. To build a smart interface for a guide robot, it is important for the system to know the user's attention. This system can detect gaze direction of the user using a real-time stereo vision system, and can recognize its position within the surrounding environment using a range sensor(More)
Since conventional correlation-based visual tracking algorithms are based on a single reference block, they often fail to track a target in the following situations: 1) a view of the target image changes, and 2) a part of the target image is occluded. This paper proposes a correlation-based visual tracking method which copes with these problems based on(More)
