A development on human interfaces aided for remote education

本项目的目标是为远程教育辅助人机界面的基本开发，我们使用大学中使用黑板或白板的常规讲座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)远程教育中摄像机视角的自动确定我们正在考虑一种新的算法，用于自动确定摄像机视角，通过Internet将讲座的运动图像传输给远程学生，它使用由计算机控制的主动摄像机，而无需摄像师。在这个项目中，我们提出了主动手势识别的算法，通过使用模糊推理和图像处理的运动图像，并确认一些讲师的实用性。(2)手写体字符识别与知识库的自动生成讨论了黑板或白板上手写体字符的分割与识别算法，以及对打印文档的表格形式等文档结构的理解算法，以建立讲座知识库。本文提出了一种新的手写体字符切分算法和一种新的表格结构分析方法，用于数字（XML）文档的翻译。

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.
