Vehicle tracking and surveillance is an area which is having a considerable attention in the context of security and safety. The detection and tacking of moving vehicles through multiple cameras is considered as a method of vehicle surveillance. This work addresses a problem of detecting and matching vehicles through multiple cameras. The power of GPUs are used to increase the number of video streams...
New communication technologies integrated into modern vehicles offer a better assistance to people injured in traffic accidents. Recent studies show how hybrid communication capabilities should be supported and improve overall rescue process. There are a variety of areas, where in a need exists for a system capable of identifying and characterize the severity of the accidents using KDD process. In...
Super resolution is a technique which is used to enhance the visual quality of a sequence of low resolution image by constructing a single high resolution image. This paper is interested in acquiring the automatic number plate recognition system from the traffic surveillance video. The proposed system detects the number plate of a vehicle from video input and then performs the super resolution technique...
The increasing popularity and acceptance of VANETs will make the deployment of autonomous vehicles easier and faster since the VANET will reduce dependence on expensive sensors. Many useful applications will be possible with the usage of VANETs, which will improve the safety and quality of trips for the owners of these vehicles. One of these applications is the avoidance of traffic congestion by smart...
An advanced vehicle monitoring and tracking system is designed for monitoring the school vehicle from any location A to location B at real time and provide safety environment to the traveler. The proposed system would make good use of new technology that based on Embedded Linux board namely Raspberry Pi and its advanced feature of storing database at real time. The proposed system works on Global...
Vehicle localization is the primary information needed for advanced tasks like navigation. This information is usually provided by the use of Global Positioning System (GPS) receivers. However, the low accuracy of GPS in urban environments makes it unreliable for further treatments. The combination of GPS data and additional sensors can improve the localization precision. In this article, a marking...
Vehicle tracking system has been extensively used for fleet management, asset tracking, surveillance, stolen vehicle recovery and many more. Advances in modern technologies like ubiquitous computing, Internet of Things (IoT) coupled with the availability of the economical hardware building blocks is creating a new wave of vehicular tracking systems. In this work we present VERTIGUO (VEhiculaR TrackInG...
This paper describes a process of converting raw Global Positioning System (GPS) data to a routable road map. In fact, it is a large scale database collected from thousands of vehicles circulating on Tunisian public roads. Moreover, the paper contains the architecture used to collect GPS data from these vehicles using GPRS connection and all the steps until getting the road traces. The data flow is...
Army logistical systems and databases contain massive amounts of data that require effective methods of extracting actionable information and generating knowledge. Vehicle diagnostics and prognostics can be challenging to analyze from the Command and Control (C2) perspective, making management of the fleet difficult within existing systems. Databases do not contain root causes or the case-based analyses...
Previous works on outdoor traffic sign recognition and classification have been demonstrated useful to the driver assistant system and the possibility to the autonomous vehicles. This motivates our research on the assistance for visual impairment or visual disabled pedestrians in the indoor environment. In this paper, we build an indoor sign database and investigate the recognition and classification...
We present a small database of “noisy” traffic signs in cluttered urban environments that exhibit various forms of degradation, including vandalism and fading (discoloration). The database contains five types of international traffic signs that allow differentiation by means of color and shape, and it has been collected in two cities in Greece. We further present a baseline system for detecting and...
Automated license plate recognition system only is not enough to detect suspicious passing vehicles. In this paper, we present a proposed framework for automated real-time detection of suspicious vehicles. It consists of two sub-systems, an automated license plate recognition system and a vehicle model recognition system. An automated license plate recognition system consists of license plate detection,...
The human face is one of the easiest characteristic, which can be used in biometric security system to identify a user. Face recognition technology, is very popular and it is used more widely because it does not require any kind of physical contact between the users and the device. Camera scans the user face and match it to a database for verification. Furthermore, it is easy to install and does not...
The spectrum database provided by FCC and Ofcom stores information about the availability of channels that can be used by vehicles to reliably transfer safety traffic information. However, due to the large number of queries to the database, the query delay could increase. In previous models, numerous modes of operation have been designed, but the communication between vehicles of different modes (particularly,...
The goal of this work is the development of a low-cost driver assistance system that runs on an ordinary smartphone. It uses computer vision techniques and multiple-resolution template matching to detect speed limit signs and alert the driver if the speed limit is exceeded. It inputs an image of the sign to be detected and creates a set of multiple-resolution templates. It also inputs photographs...
This paper presents a novel Information and Com- munication Technology solution that enables the implementation of the vehicle to grid concept. The integration of electric vehicles in smart grids introduces new challenges taking into account their intrinsic mobility beyond the reach of the home area network. In order to overcome this problem, new communication applications were developed to monitor...
A tool for battery system virtual prototyping based on an empirical model and a database has been developed. Battery cell characteristics are gathered and correlated with specific scaling laws, then used to build a battery pack meeting a set of target requirements. The corresponding pack model is then created to be used in a system simulation platform to evaluate the vehicle behavior with prototyped...
This paper studies the problem of matching images captured from an unmanned ground vehicle (UGV) to those from a satellite or high-flying vehicle. We focus on situations where the UGV navigates in remote areas with few man-made structures. This is a difficult problem due to the drastic change in perspective between the ground and aerial imagery and the lack of environmental features for image comparison...
Tauxschema is a framework for constructing and validating time-varying XML documents through the use of a temporal schema. This latter ties together a conventional schema (i.e., A standard XML Schema document) and its corresponding logical and physical annotations, which are stored in an annotation document. Conventional schema and logical and physical annotations undergo changes to respond to changes...
Current GPS-based devices have difficulty localizing in cases where the GPS signal is unavailable or insufficiently accurate. This paper presents an algorithm for localizing a vehicle on an arbitrary road network using vision, road curvature estimates, or a combination of both. The method uses an extension of topometric localization, which is a hybrid between topological and metric localization. The...
