Visual tracking of human movement has attracted increasing attention recently because of its wide spectrum of applications, including athletic and clinical performance analysis, human-computer interface, surveillance, motion capture for games and animation. There are two main techniques in the visual tracking of the human movement community: marker-based tracking and marker-free tracking. This ...

Interhemispheric competition between homologous areas in the human brain is believed to be involved in a wide variety of human behaviors from motor activity to visual perception and particularly attention. For example, patients with lesions in the posterior parietal cortex are unable to selectively track objects in the contralesional side of visual space when targets are simultaneously present ...

In this paper, we present a generic and flexible system for vision-based robot control. The system integrates several research areas (visual matching, visual tracking and visual servoing) in a unifying framework. In this framework, the flexibility is obtained using a template matching algorithm based on an efficient second-order minimization. Contrarily to feature-based visual servoing schemes,...

OF THESIS Joint Visual and Wireless Tracking System Object tracking is an important component in many applications including surveillance, manufacturing, inventory tracking, etc. The most common approach is to combine a surveillance camera with an appearance-based visual tracking algorithm. While this approach can provide high tracking accuracy, the tracker can easily diverge in environments wh...

This paper presents a real-time visual tracking system in the robot soccer domain. The details of the Essex Wizards robot football team and its control system are described. A real-time visual tracking algorithm has been developed. Some initial results of the image pre-processing and visual tracking algorithms in real environment setting are given to show the performance of the system.

Visual field deficits due to optic radiation injury are a common complication of temporal lobectomy in epilepsy surgery. In this prospective study, diffusion tensor imaging (DTI) based fiber tracking was performed on 48 patients who had temporal lobectomy for pharmaco-resistant epilepsy. Pre- and intra-operative DTI based fiber tracking was used to visualize the optic radiation and to predict t...

Tracking is an important processing step for many single and multi-camera applications such as sports video analysis, traffic monitoring and event detection. In the first part of the paper, we present a framework of visual tracking using first-order Markov state-space model. We subsequently use Sequential importance Sampling method to estimate the posterior density and obtain the firstorder par...
