    Abstract-We describe a new method for High Dynamic Range (HDR) Video using alternating exposures that adds no additional cost or bandwidth requirements to individual IP cameras, making it suitable for large scale security and surveillance systems. Sufficient dynamic range is crucial to the efficacy of a surveillance system, as saturated pixels mean a camera can no longer "see" its surrounding environment. High costs associated with hardware for improved dynamic range make them unsuitable for very large networks with hundreds or even thousands of cameras. We outline a scalable software method that uses post-processing to combine the information in adjacent frames of a video sequence captured with alternating short and long exposures. In particular, we introduce a novel bi-directional motion estimation module that utilizes block-based motion vectors to register frames with large differences in global brightness and fast local motion within saturated regions. An HDR post-processing solution can be deployed at a central location to process individual camera streams on an "as needed" basis, removing additional costs at the device-end. Furthermore, cameras continue to transmit low dynamic range frames, so there is no additional bandwidth requirement. Results show significant gains in video quality for inexpensive cameras when exposed to brightness variations common in security and surveillance

    The European Security Industry: A Research Agenda

    The security industry can be defined, in the first instance, as the industry that produces the goods and services required to protect citizens from insecurity. Yet, this industry, as opposed to defence, has not been an area of intense research. Their boundaries are unclear and the industry is not well characterised. This paper analyses this knowledge gap and presents some ideas for a research agenda for this industry that could assist in unveiling the main features, the potential weaknesses and strengths, and the capability to solve the security needs of society in an efficient and effective way. The paper discusses a definition of this economic sector useful in setting its boundaries, and it briefly describes the main types of industries operating within the sector. It analyses methods for gathering information regarding the industry, customers, and other market agents. Finally, it outlines ways for assessing market performance in terms of the structure-conduct-performance paradigm.security industry, security market, terrorism and organised crime countermeasures, competition, market performance

    A feasibility study: California Department of Forestry and Fire Protection utilization of infrared technologies for wildland fire suppression and management

    Get PDF
    NASA's JPL has completed a feasibility study using infrared technologies for wildland fire suppression and management. The study surveyed user needs, examined available technologies, matched the user needs with technologies, and defined an integrated infrared wildland fire mapping concept system configuration. System component trade-offs were presented for evaluation in the concept system configuration. The economic benefits of using infrared technologies in fire suppression and management were examined. Follow-on concept system configuration development and implementation were proposed

    An intelligent surveillance platform for large metropolitan areas with dense sensor deployment

    Producción CientíficaThis paper presents an intelligent surveillance platform based on the usage of large numbers of inexpensive sensors designed and developed inside the European Eureka Celtic project HuSIMS. With the aim of maximizing the number of deployable units while keeping monetary and resource/bandwidth costs at a minimum, the surveillance platform is based on the usage of inexpensive visual sensors which apply efficient motion detection and tracking algorithms to transform the video signal in a set of motion parameters. In order to automate the analysis of the myriad of data streams generated by the visual sensors, the platform’s control center includes an alarm detection engine which comprises three components applying three different Artificial Intelligence strategies in parallel. These strategies are generic, domain-independent approaches which are able to operate in several domains (traffic surveillance, vandalism prevention, perimeter security, etc.). The architecture is completed with a versatile communication network which facilitates data collection from the visual sensors and alarm and video stream distribution towards the emergency teams. The resulting surveillance system is extremely suitable for its deployment in metropolitan areas, smart cities, and large facilities, mainly because cheap visual sensors and autonomous alarm detection facilitate dense sensor network deployments for wide and detailed coveraMinisterio de Industria, Turismo y Comercio and the Fondo de Desarrollo Regional (FEDER) and the Israeli Chief Scientist Research Grant 43660 inside the European Eureka Celtic project HuSIMS (TSI-020400-2010-102)

    Regional Data Archiving and Management for Northeast Illinois

    This project studies the feasibility and implementation options for establishing a regional data archiving system to help monitor and manage traffic operations and planning for the northeastern Illinois region. It aims to provide a clear guidance to the regional transportation agencies, from both technical and business perspectives, about building such a comprehensive transportation information system. Several implementation alternatives are identified and analyzed. This research is carried out in three phases. In the first phase, existing documents related to ITS deployments in the broader Chicago area are summarized, and a thorough review is conducted of similar systems across the country. Various stakeholders are interviewed to collect information on all data elements that they store, including the format, system, and granularity. Their perception of a data archive system, such as potential benefits and costs, is also surveyed. In the second phase, a conceptual design of the database is developed. This conceptual design includes system architecture, functional modules, user interfaces, and examples of usage. In the last phase, the possible business models for the archive system to sustain itself are reviewed. We estimate initial capital and recurring operational/maintenance costs for the system based on realistic information on the hardware, software, labor, and resource requirements. We also identify possible revenue opportunities. A few implementation options for the archive system are summarized in this report; namely: 1. System hosted by a partnering agency 2. System contracted to a university 3. System contracted to a national laboratory 4. System outsourced to a service provider The costs, advantages and disadvantages for each of these recommended options are also provided.ICT-R27-22published or submitted for publicationis peer reviewe
