信息检索综合报告 姓名: 李鸿鹏 学号: 2008040201135 学院: 空军后备军官学院 2010 年 06 月 20 日 课题名称（中文）: 手指书写:一种虚拟文字识别人机交互新方法 课题名称（英文）： Finger Writing:A Novel Virtual Character Recognition HCI Approach 课题重点、关键词、主题词等分析（中英文）： 课题重点：一种全新的手指书写虚拟文字识别系统,该系统利用摄像头捕捉人手指的运动轨迹,通过手指跟踪及检测算法,恢复出手指虚拟"书写"文字的二维图像数据(称之为虚拟文字),再进行识别输出.文中对单层函数连接神经网络进行改进并用来进行高准确度的运动手指尖的预测及跟踪,给出了一种基于数学形态学及模板匹配的简单有效的手指检测方法,提出了基于运动手指跟踪的"虚拟文字"恢复方法.实验结果表明:系统方案可行,手指跟踪及检测准确率高,对手指"书写"的数字、英文等虚拟文字识别率能达到 95%以上.( Write a new finger virtual character recognition system, the system uses cameras to capture the trajectory of human fingers by finger tracking and detection algorithm, the recovered finger virtual "writing" two-dimensional image of text data (known as virtual characters ) and then identify the output. article on single function link neural network to improve and is used for high accuracy prediction finger movement and tracking, are given a template matching based on mathematical morphology and a simple and effective detection of finger method is proposed based on finger movement tracking "virtual text" recovery method. Experimental results show that: the system is feasible, finger tracking and detection of high accuracy, on the fingers "writing" numbers, English and other virtual character recognition rate can reach 95% above.) 关键词及主题词：手指书写（finger writing）：利用手写的形式输入。（Use the form of handwritten input）虚拟文字识别（virtual character recognition）：该系统可对手写的虚拟文字进行准确的识别。（The system can hand-written text and accurate identification...
