课程名称：数字视频处理及通信系列讲座— Multimedia Communication over the Internet and over wireless
主讲人: 吴大鹏 博士
时 间: 12月22日 15:00－17：00
地 点: 六教6A116
课程介绍：本次讲座是吴大鹏博士数字视频处理及通信课程的系列讲座之一，主要以《Digital Video Processing and Communication》教材为基础，内容包括视频处理与通信基础及其前沿研究课题和方向，主题为Internet及无线环境下的多媒体通信。
A wireless video sensor network (WVSN) is a system of spatially　distributed video sensors which gather and transmit video information　over a wireless ad hoc network. To measure, control and optimize the　system performance, the following key research problems need to be addressed:
1) how to measure the amount of visual information collected by the video sensor within its operational lifetime?
2) how to quantitatively compare the information sensing efficiency between two video sensors?
3) how to measure the information sensing efficiency of the whole video sensor network?
4) how to control and optimize the information sensing efficiency of the video sensor network?
In this talk, I will introduce the concept of accumulative visual information (AVI), and use it to optimize the efficiency of the WVSN system.
