This work proposes an intelligent and interactive virtual fence system for security management in a danger-or accident-prone area. The proposed system is designed to be realized in an outdoor and wide-area park. With the proposed system, users can visually and arbitrarily define the polygonic alert area for the sake of security. The Gaussian Mixture Model (GMM) and AdaBoost algorithms are modified...
Humans are still responsible for operating complex equipment because they are able to respond during emergency situations. By removing the pilot from an aircraft, Unmanned Air Vehicles (UAVs) are vulnerable to unpredictable activity within their environment. The landing process is the most stressful phase of flight for pilots and as a consequence, a significant number of UAV are being destroyed or...
Novel computing systems are increasingly being composed of large numbers of heterogeneous components, each with potentially different goals or local perspectives, and connected in networks which change over time. Management of such systems quickly becomes infeasible for humans. As such, future computing systems should be able to achieve advanced levels of autonomous behaviour. In this context, the...
In this paper an audio-video system for intelligent environments with the capability to recognize people is presented. Users are tracked inside the environment and their positions and activities can be logged. Users identities are assessed through a multimodal approach by detecting and recognizing voices and faces through the different cameras and microphones installed in the environment. This approach...
In traffic surveillance applications, automatic methods to detect abrupt changes in a traffic scene are highly desirable. A robust method is introduced for camera based assessment of scene changes based on the dynamics derived from the detected objects in the scene. The approach needs a calibrated and oriented camera but no further contextual knowledge and works even with highly fragmented trajectories...
In this paper, we introduce a new active information display system which is based on Intelligent Space and a projector mounted mobile robot. This system is able to afford a human with relevant information by projecting it on where the human is looking such as a wall, a floor, and a door. For this system, Intelligent Space should recognize location of human. To estimate position of human in Intelligent...
People are capturing and storing an ever-increasing amount of information about themselves, such as digital images. New technologies, in addition to increasing the need to store daily activities via images and for retrieval capacity, have led to the development of interaction methods for this information. Therefore, this case study suggests an Artificial Mirror interaction system to enable access...
Human posture recognition is gaining increasing attention in the fields of artificial intelligence and computer vision due to its promising applications in the areas of personal health care, environmental awareness, human-computer-interaction and surveillance systems. Human posture recognition in video sequences is a challenging task which is part of the more comprehensive problem of video sequence...
An ??agent?? in a computer simulation is an object with a dynamic model driving its actions. There are different classifications for agents, for example: autonomous, intelligent, and software. A cell within a cellular automaton might be considered an agent with the complete environment being a multi-agent system. An object containing an artificial intelligence could also be considered an agent. Our...
This paper outlines the framework of a complex system to demonstrate multimodal spatial and transactional intelligence in a robot which supports aged, frail, or otherwise disabled people in a domestic assistive technology context. The intention is that the robot be able to navigate around a known multi-room environment along optimal, collision-free paths in search and retrieval of requested objects...
In this paper we present an integrated system for intelligent video surveillance, control and alarm generation in security applications related to protection of public buildings (e.g. various financial institutions). By using only two networked cameras, video information is collected, dispatched via network and processed on-line with a group of integrated image processing algorithms able to detect...
This paper presents a three-dimensional virtual registration for human motion analysis. We will focus on constructing 3D visualization of human body from different views of the cameras. The 3D representation then can be used for medical diagnosis such as for evaluation and analysis for people who have walking difficulties and require rehabilitation therapy. This can help to identify specific reasons...
