The research of Video Streaming has often focused on the methodologies of P2P protocols, such as peer selection, network structure, group organization, etc. In addition, streaming mechanism and system deployment are significant to provide a Video Streaming service. Research in this field, however, is scant. On the other hand, the layered video codec provides scalability when environment is dive...

SoundSpotter is an open source software system for real-time matching of an audio input stream to a database of continuous audio or video. Among its novel features are real-time control over audio segmentation, feature selection and match radius. The system uses audio input to control selection of output from a database using similarity-based matching. The low latency methods employed create a ...

This chapter investigates HTTP video streaming over the Internet for the YouTube platform. YouTube is used as concrete example and case study for video delivery over the Internet, since it is not only the most popular online video platform, but also generates a large share of traffic on today’s Internet. We will describe the YouTube infrastructure as well as the underlying mechanisms for optimi...

The focus of this chapter is to present a survey on the most recent advances in representation and analysis of video object trajectories, with application to indexing and retrieval systems. We will review the main methodologies for the description of motion trajectories, as well as the indexing techniques and similarity metrics used in the retrieval process. Strengths and weaknesses of differen...

A video tracking system raises a wide possibility in today’s society. This system is used in various applications such as security, monitoring, robotic, and nowadays in day-to-day applications. However the video tracking systems still have many open problems and many of research activities in a video tracking system are explored. Therefore in this article, an overview of recent research activit...

A system for detecting and analyzing behavior of a sports person from their facial expression extracted from a sports video from the basis of this project. Shot Segmentation, Object Frame Selection, Image Segmentation, Facial Feature Extraction and Facial Expression Recognition (FER) are the major steps included in developing Cognitive Analysis of Facial Expression Recognition system from Sport...

The intensification of transport in the urban environment has generated an increase oflevel noise. Therefore, the EC has implemented an environmental policy for the reducing the noiselevel. Thus, the limit values acceptable for the noise levels in urban areas are 50 dB. To determine the noise level for these environments were designed and made various systems to measure level of noise, the majo...

Current video-surveillance systems typically consist of many video sources distributed over a wide area, transmitting live video streams to a central location for processing and monitoring. The target of this paper is to present an experience of implementation of a large-scale video-surveillance system based on a wireless mesh network infrastructure, discussing architecture, protocol, and imple...
