A Study of Interactive Video-Lecture System for Practical Use

开发了一个电子学习系统，它自动记录粉笔对话讲座，交付给学生，并检查学生的理解水平。该系统从一块普通黑板前录制的粉笔讲座视频中自动生成电子学习材料。改进了ChalkTalk核心模块的运动目标识别准确率，实现了Android操作系统和HTML5浏览器(Android、iOS、Windows、MacOS、LinuxOS)的播放器。

An E-learning system that automatically records chalk-talk lectures, delivers to the students, and check the level of understanding was developed. The system automatically produces E-learning materials from a videotaped chalk talk lecture in front of an ordinary blackboard. As results, the moving object recognition accuracy of ChalkTalk core module was improved, and players for Android OS and HTML5 browsers (for Android, iOS, Windows, MacOS, in LinuxOS) were implemented.
