11 Aug 2005TL;DR: In this paper, a coordinated surveillance system uses a larger number of fixed low resolution detection smart camera devices and a smaller number of pan/tilt/zoom controllable high resolution tracking camera devices.
Abstract: A coordinated surveillance system uses a larger number of fixed low resolution detection smart camera devices and a smaller number of pan/tilt/zoom controllable high resolution tracking smart camera devices. The set of detection cameras provide overall continuous coverage of the surveillance region, while the tracking cameras provide localized high resolution on demand. Each monitor camera device performs initial detection and determines approximate GPS location of a moving target in its field of view. A control system coordinates detection and tracking camera operation. A selected tracking camera is controlled to focus in on, confirm detection, and track a target. Based on a verified detection, a guard station is alerted and compressed camera video is forwarded to the guard station from the camera(s). The guard station can direct a patrol guard to the target using GPS coordinates and a site map.

TL;DR: In this paper, a packet loss frequency computation part (102) counts packet losses which have been generated in a specified interval expressing the interval of continuous IP packets as packet losses of one time from an extracted packet loss pattern, and computes the counted value as a packetloss frequency.
Abstract: A packet loss frequency computation part (102) counts packet losses which have been generated in a specified interval expressing the interval of continuous IP packets as packet losses of one time from an extracted packet loss pattern, and computes the counted value as a packet loss frequency. Moreover, the packet loss frequency computation part (102) computes a burst packet loss length expressing the number of continuously lost packets from the packet loss pattern. An average burst packet loss length within a quality estimation interval is computed from the burst packet loss length, and a packet loss variation index computation part (106) derives a packet loss variation index from the average burst packet loss length. Meanwhile, an encoding quality computation part (103) computes an encoded image quality value based on an extracted encoding bit rate and frame rate. An image quality estimation part (104) computes the encoded image quality value, the packet loss frequency, and the packet loss variation index. Thereby, the quality of the image in which a burst packet loss has occurred can be correctly estimated.

TL;DR: In this article, key performance indicators that are necessary to properly measure the health of video surveillance applications and the supporting infrastructure are disclosed, including Video Path Uptime (VPU), Video Stream Delivery Index (VSDI), and Video Retention Compliance (VRC).
Abstract: Key performance indicators that are necessary to properly measure the health of video surveillance applications and the supporting infrastructure are disclosed. The performance indicators include: Video Path Uptime (VPU), Video Stream Delivery Index (VSDI), and, Video Retention Compliance (VRC). From these metrics, it is possible to calibrate whether the surveillance infrastructure is operating properly. These metrics can be used to properly alert video network administrators of problems that are actually affecting the video surveillance application. It is also possible to use these metrics to build better analytics to determine root cause of problems as well as build prediction models for potential problems before they occur

Abstract: A method and apparatus for measuring the quality of a video is provided. The method comprises: generating a frame loss pattern of the video by indicating whether each frame in the video is lost or successfully transmitted; and evaluating the quality of the video as a function of the generated t came loss pattern.
