A development on human interfaces aided for remote education

本项目的目标是为远程教育的人机界面做一个基本的开发，我们正在使用大学里通常使用的黑板或白板来制作远程教育的内容。本课题包括以下两个方面的基础研究：(1)远程教学中摄像机视点的自动确定我们正在考虑一种新的摄像机视点自动确定算法，将讲座的动态图像通过Internet传输到远程学生，它使用计算机控制的主动摄像机，而不需要摄像人员。本课题提出了基于模糊推理和运动图像处理的主动手势识别算法，并通过部分讲师的实验验证了算法的实用性。(2)手写字符识别与知识库的自动生成讨论了黑板或白板上手写字符的分割与识别算法，以及印刷文档表格等文档结构的理解算法，建立了讲座上的知识库。提出了一种新的触摸手写字符切分算法和一种用于数字(XML)文档翻译的表结构分析方法。

The goal of this project is a basic development on human interfaces aided for remote education, and we are using the usual lectures using the blackboard or whiteboard in university to make the contents of remote education. The project includes two following basic researches.(1) Automatic determination of the camera view to remote educationWe are considering the new algorithm for the automatic determination of the camera view to transmit the moving images of the lecture to remote students via the Internet, and it uses active camera controlled by computer without cameraman. In this project, we proposed the algorithm of active gesture recognition by using fuzzy reasoning and image processing by the moving images, and confirm the usefulness by some lecturers.(2) Handwritten character recognition and the automatic generation of knowledge databaseWe discussed the segmentation and recognition algorithm of handwritten characters on blackboard or whiteboard, and the understanding algorithm of the document structure such as the table form for printed document to make the knowledge database on the lecture. We proposed a new segmentation algorithm for touching handwritten characters and a new analysis method for table structures to translate digital (XML) documents.
