This paper investigates quality monitoring of videos transmitted over packet networks. Our goal is to develop a methodology that is both simple and accurate to support quality assessment for videos over packet networks. For this purpose, this paper focus on the parameters that affect the quality of videos and uses back propagation Neural Networks (BP-NN) to mimic the way that human viewers asse...

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...

Time series prediction techniques have been shown to significantly reduce the radio use and energy consumption of wireless sensor nodes performing periodic data collection tasks. In this paper, we propose an implementation of exponential smoothing, a standard time series prediction technique, for wireless sensors. We rely on a framework called Adaptive Model Selection (AMS), specifically design...

In recent decades, many government agencies and famous universities are researching the intelligent traffic video monitoring system. According to the tunnel monitoring video, this paper uses the combination of background subtraction method and three frame differencing method for moving vehicle detection , and designs the geometric parameters and combined parameters for vehicle classification, f...

The monitoring and videoing of a user’s movement within a “FieldLab” recreational facility is required to study the effectiveness of innovative equipment designed to increase physical activity. A low cost alternative to current tracking systems based around the Global positioning system (GPS) was trialed for use within the Sheffield FieldLab. This low cost tracking system is based around a typi...

With the development of network technology, multimedia applications in various video forms are widely used in network services. In order to leverage video QoS, it becomes a pressing problem to monitor and control video QoS during network transmission of video. In this paper, we propose a monitoring and control framework for video QoS over IP and mobile network. Also, we develop a low computatio...

The nodes of wireless sensor network are mainly responsible for the collection and processing of the information and send to neighboring nodes. The paper presents design and development of multimedia video monitoring system based on wireless sensor network. Video monitoring system is designed to analysis and judgment of target behavior in the scene, so that let the computer correctly understand...
