This paper proposes novel algorithms and system architecture for tracking targets in video streams. The proposed system comprises a variation of Stauffer’s adaptive background algorithm with spacio-temporal adaptation of the learning parameters and a Kalman tracker in a feedback configuration. In the feed-forward path, the adaptive background module provides target evidence to the Kalman tracke...

The neural extended Kalman filter is a technique that learns unmodelled dynamics while performing state estimation. This coupled system performs the state estimation of the plant while estimating a function approximation of the difference between the system model and the dynamics of the true plant. At each sample step, this approximation is added to the existing model improving the state estima...

Purpose – The purpose of this work is to investigate the use of a laser tracker, a laser interferometer system and a telescopic ballbar for assessing the positioning performance of a six-axis industrial serial robot. The paper also aims to illustrate the limitations of these three metrology instruments for the assessment of robot positioning performance and to demonstrate the inadequacy of simp...

The problem of consciousness has captured the imagination of philosophers, neuroscientists, and the general public, but has received little attention within AI. However, concepts from robotics and computer vision hold great promise to account for the major aspects of the phenomenon of consciousness, including philosophically problematical aspects such as the vividness of qualia, the first-perso...

This paper addresses object detection and tracking in high-resolution omnidirectional images. The foreseen application is a visual subsystem of a rescue robot equipped with an omnidirectional camera, which demands real time efficiency and robustness against changing viewpoint. Object detectors typically do not guarantee specific frame rate. The detection time may vastly depend on a scene comple...

Remotely operated robots, functioning in hazardous and time critical environments, have significant requirements for control and visual information (Davids (2002), Murphy (2004)). The control systems are supposed to guarantee a precise timely response in order to prevent fatal scenarios in bomb disposal operations or in life rescue missions. Significant role to these operating scenarios play th...

In this paper we address the issue of Computer Vision in Antarctica for robot navigation by analysing images collected at Patriot Hills, Antarctica in the Fall of 1998. Conditions produced by polar weather and terrain are unique and challenging for perception equipment and computer vision algorithms. The later aspect will be studied here through the evaluation of a colour segmentation algorithm...

The paper describes a complete framework for autonomous environment mapping, localization and navigation using exclusively monocular vision. The environment map is a mosaic of 2D patterns detected on the ceiling plane and used as natural landmarks. The robot is able to localize itself and to reproduce learned trajectories defined by a set of key images representing the visual memory. A specific...

This paper proposes a free-viewpoint interface for mobile-robot teleoperation, which provides viewpoints that are freely configurable by the human operator head pose. The viewpoints are acquired by a head tracker equipped on a head mounted display. A real-time free-viewpoint image generation method based on view-dependent geometry and texture is employed by the interface to synthesize the scene...

This paper deals with the problem of cooperative localization for the case of large groups of mobile robots. A Kalman filter estimator is implemented and tested for this purpose. The focus of this paper is to examine the effect on localization accuracy of the number N of participating robots and the accuracy of the sensors employed. More specifically, we investigate the improvement in localizat...
