This paper proposes a method for the visual-based navigation of a mobile robot in indoor environments, using a single omni-directional (catadioptric) camera. The geometry of the catadioptric sensor and the method used to obtain a bird’s eye (orthographic) view of the ground plane are presented. This representation significantly simplifies the solution to navigation problems, by eliminating any ...

This paper investigates the possibility of augmenting an Unmanned Aerial Vehicle (UAV) navigation system with a passive video camera in order to cope with long-term GPS outages. The paper proposes a vision based navigation architecture which combines inertial sensors, visual odometry and registration of the on-board video to a geo-referenced aerial image. The vision-aided navigation system deve...

Genetic Programming techniques can be used to produce regression equations that quantify emotional expressions on a facial model. The formulae give emotional scores based on the position of 25 automatically generated “landmarks” on the face. The method shown here is an integrated part of a system that maps multidimensional data sets to naturalistic visual structures such as a face.

Given the high relevance of visual input to human behavior, it is often important to precisely monitor the spatial orientation of the visual axis. One popular and accurate technique for measuring gaze orientation is based on the dual search coil. This technique does not allow for very large displacements of the subject, however, and is not robust with respect to translations of the head. More r...

Robot vision is usually based on well-calibrated system in which the large numbers of calibration parameters cause error-prone and imprecise behaviour of the system. The fact that humans use a visual feedback intuitively initiated efforts to develop the robot control system based on agents for 3D control of robot arm without calibration. Using the simulator of 3-segment robot arm, the operators...

Head motion is a common cause of technical failure in functional magnetic resonance imaging. A simple visual alignment system has been developed to provide visual feedback to the subject about his or her head position. The subject is able to readjust his or her head position accurately during a study, should motion occur. This sighting system is incorporated into a visor that fits onto the comm...
