Designing a robust tracking control for a non-linear MIMO system with uncertainty is one of the most complicated control problems. In this paper, sliding mode changed to non-linear controllable canonical form by input-output linearization. This, sliding surfaces can be defined in a way that we can de-couple equations and indicate the sliding conditions of multi-variable controller system. The u...

Multicamera vehicle tracking is a necessary part of any video-based intelligent transportation system for extracting different traffic parameters such as link travel times and origin/destination counts. In many applications, it is needed to locate traffic cameras disjoint from each other to cover a wide area. This paper presents a method for tracking moving vehicles in such camera networks. The...

with the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. tracking people as they move through a camera network with non-overlapping field...

Shaping is a way in which a human designer can provide assistance to a learning system to enable it to solve problems that would otherwise defeat it. Results are presented showing that shaping can significantly improve the final performance of controllers evolved for a difficult visual tracking task. Controllers are developed in simulation and then transferred to a real robot head.

The problem of eye gaze tracking has been researched and developed for a long time. The most difficult problem in the non-intrusive system of eye gaze tracking is the problem of head movements. Some of existing methods have to use two cameras and an active infrared (IR) illumination to solve this problem. Otherwise, with a single camera, the user has to hold the head uncomfortably still when pe...

This paper addresses the accuracy problem of an eye gaze tracking system. We first analyze the technical barrier for a gaze tracking system to achieve desired accuracy, and then propose a subpixel tracking method to break the barrier. We present new algorithms for detecting the inner eye corner and the center of an iris in subpixel accuracy, and we apply these new methods in developing a real-t...

In this paper, we investigated the effects of guided and unguided style VR learning on user attention and retained knowledge. We conducted a study where users performed guided or unguided style learning in the virtual environment while user attention was measured through an eye tracking system and physiological sensors. The virtual environment contained the five specific events associated with ...

the aim of the present study was to investigate the effects of various scheduled practices (self-regulated and non-self-regulated) on the acquisition, retention and transfer of simple and complex tracking tasks. 96 right-handed undergraduate students (age rang: 18-24 years old) volunteered to participate in this study (48 females, 48 males). these students participated in physical education cla...
