本文完成了对唇动身份识别技术几个基本问题的理论研究,并对整个系统加以实现.作为本文研究的实验基础,我们建立了唇动方式身份识别数据库(HITLUDB), 该库目前包含30个说话人每人20个汉语词的音视频语料.数据库的扩充与完善工作仍在不断的进行之中.在嘴唇检测方面, 我们对自适应色度过滤模型进行改进,提高了算法的鲁棒性,完成了对嘴唇的精确定位.结合DCT变换与K-L变换的各自特点, 我们提出了特征提取算法,使用较少维数的特征完成了对嘴唇区域主要信息的刻画.由于唇动信息同时包含了生理特征与行为特征, 我们使用静念动念混合建模的方式,完成了对说话人唇动个性特点的精确描述.在HMM训练时,我们提出了特征的归一化处理方法,提高了HMM在实际应用中的性能. 最后,我们分别对身份辨认系统与身份确认系统的基本理论进行了叙述,并完成了系统的实践工作. 关　 键　 词：身份识别 唇动 特征提取 隐马尔可夫模型 K-L变换 -paper completed the lip movements identification technology several basic issues of theoretical study, system as a whole be achieved. As this paper, the experimental basis, We have established a dynamic manner lip identification database (HITLUDB) The library currently contains 30 words each of 20 Chinese words, sound and video corpus. and the expansion of the database is still perfect keep going on. Detection of the lips, we adaptive color filter model improvements, improve the robustness of the algorithm, completed a pair of lips the precise positioning. DCT combined with

曲线拟合涉及回答两个基本问题: 最佳拟合意味着什么？应该用什么样的曲线？可用许多不同 的方法定义最佳拟合, 并存在无穷数目的曲线. 所以, 从这里开始, 我们走向何方？正如它证实的那 样, 当最佳拟合被解释为在数据点的最小误差平方和, 且所用的曲线限定为多项式时, 那么曲线拟 合是相当简捷的.-Curve fitting involves answering two fundamental questions: What does it mean for the best fit? What should be the kind of curve? Available in many different ways to define the best fitting, and the existence of infinite number of curves. So, from here on, we going? As it proved, when the best fit is interpreted as data points in the smallest error sum of squares, and used to be limited to polynomial curve, then curve fitting is very simple.
