Abstract : We present an efficient reduced−reference video quality assessment method based on local harmonic strength (LHS) feature. LHS is based on harmonics gain and loss information extracted from picture that correspond with the two most prominent compression artifacts, blockiness and blurriness. Efficiency is achieved through further reduction of the reduced−reference overhead. For the LHS...

With the development of substation automation technology, unmanned substation operation mode has become a trend, at present, many substations to achieve the "remote viewing" function, will be the scene of the substation, the equipment state to video image transmission to the remote control center (set control station). And scheduling center (set control station) on live video equipment to contr...

This document describes system-level issues for incorporation of multi-rate video into a videoon-demand system. The issues are broadly separated into two classes: rate negotiation, involving selection of a rate at which the requested video will be provided, and rate delivery, involving delivery of the coded stream to the user. Requirements of the server, the network, and the set-top box are dev...

Shoreline stability is an important issue along much of the Mediterranean’s Coasts. European project MEDDOOC INTERREG BEACHMED-e focused on the strategic management of beach protection for the sustainable development of the Mediterranean coastal zone. In the framework of this project, a video system has been installed in Valras (Gulf of Lions / France) to monitor coastal evolutions and recent p...

With the rapid development of wireless networks and image acquisition technology, wireless video transmission technology has been widely applied in various communication systems. The traditional video monitoring technology is restricted by some conditions such as layout, environmental, the relatively large volume, cost, and so on. In view of this problem, this paper proposes a method that the m...

Wireless sensor ad-hoc network usually applied in a monitoring system like monitoring temperature, humidity or even any triggering inputs from a connected peripheral device. The approach of wireless ad hoc network for monitoring video data is under preliminary investigation and development because video streaming requires larger storage, quality channel, less jittering and low packet loss. The ...

In recent years, the number of the cases of information leaks is increasing. Companies and Research Institutions make various actions against information thefts and security accidents. One of the actions is adoption of the crime prevention system, including the monitoring system by surveillance cameras. In order to solve difficulties of multiple cameras monitoring, we develop the automatic huma...

Robust and reliable traffic monitoring system is an urgent need to improve traffic control and management. Vehicle flow detection appears to be an important part in traffic monitoring system. The traffic flow shows the traffic state in fixed time interval and helps to control the traffic. This paper proposes an automatic traffic monitoring system which is used for estimating the important traff...

This paper aims at analyzing the design and the realization process of PLC practical teaching device developed by the configuration technology. Specifically, t1his practical teaching device employs the teaching monitoring interface developed by the configuration software to communicate with the programmable controller so as to realize such functions as system login, question type selection and ...
