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.

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

随着各行各业的发展和生产的需要,工业的发展和生产的需要。
随着各行各业的发展和生产需要,业界上的采集器已经满足不了某些行业的生产需要,他们不仅需要采集数据还需将数据发生变化的时间记录下来,断电数据不掉失,特别是当电脑读取采集器的数据时还需能继续采集数据,保证不掉失一个数据,并且还要求擦除采集器旧的数据时还能继续采集数据和保存数据,保证不擦除新的数据,因为某些场合需要时时刻刻不间断的采集数据,并要求任何时刻都能读取数据。 -With the development and production of all walks of life needs of the industry on the collector has been unable to meet the needs of certain sectors of production, they require not only data collection will need to change the time data recorded, the data can not lose power, especially is when the computer read the data collector can continue to collect data needed to ensure that a data can not lose, and also requires the collector erase the old data will continue to collect data and save data to ensure that does not erase the new data, because some occasions the need for uninterrupted data collection at all times and request at any time be able to read data.
