Computer Aided System of Intelligent Contents Generation for Individual Interactive Education

本研究项目提出了以下具有挑战性的方法：(1)大课堂中主动摄像机视角下的动态判定方法和在线学习场景分割算法针对大班中主动摄像机视角下的动态判定方法，提出了一种基于教师行为的动态判定算法，减少了摄像机视点的运动时间。针对交互式网络学习内容的生成，提出了两种场景分割方法。第一种方法是基于黑板状态，第二种方法是基于非语音声音。(2)黑板上手写关键词的识别和高分辨率图像的生成利用黑板上字符的关键词词典开发了手写关键词识别算法。针对大班黑板图像的特点，提出了一种新的大班黑板图像阈值方法“中值差值法”和一种新的高分辨率黑板图像生成方法“遗传图像合并算法”。(3)纸质文档数字化方法及个性化交互教育系统的开发在高等教育中，学生对现实世界中的各种内容感兴趣，但数字化所需的大量信息却没有被打开，信息的缺乏是数字化学习中的重要问题之一。我们正在挑战从纸质文档到数字文档的自动翻译，我们开发了。一种新的从纸质文档中提取文档结构的方法。并利用翻译后的数字文档开发了个性化互动教育系统

This research project developed the following challenging approaches.(1) Dynamic determination method in the view of an active camera in large rlacc and scene segmentation for e-leaningAnew algorithm based on the behavior of a teacher is proposed for a dynamic determination method in the view of an active camera in large class, and the algorithm reduced the motion time of camera view. Two approaches are proposed for scene segmentation for generation the interactive e-learning contents. The first approach is based on the blackboard state, and the second approach is based on anon-voice sound.(2) Handwritten keyword recognition on the blackboard and the generation of high resolution imageHandwritten keyword recognition algorithms are developed using keyword lexicon for the characters on the blackboard. A new kcal threshold method "median differential method" and a new generating method "genetic image merge algorithm" of the high resolution image are proposed for the blackboard image in large class(3) Digitizing method for paper documents and the development of an individual interactive education systemIn higher education, the student interests in the various contents in real world, but a lot of required information is not opened for the digitizing coat The lack of the information is one of important problems in e-learning. We are challenging the automatic translation from paper documents to digital documents, and we developed. a new extracting the document structure from a paper document. And we developed the individual interactive education system licitly the translated digital documents
