唇读

The topic of this paper is about the design of Bimodal Database for continuous Lip-Reading and the research on its material segmentation.

论文对适合唇读研究的连续音节双模态语料库及其语料切分算法的设计和研究工作进行了讨论。

The last part of this paper gives concluding remarks.

论文最后对全文进行了总结并对唇读技术的发展进行了展望。

The purpose of mouth shape classification is to confirm the mumber of states, shrink searching space and expedite convergence speed for lipreading recognition.

本文的目的是在此分类的基础上，明確唇读识别阶段的状態数，减小搜索的空间，提高收敛速度。

If I do not succeed they resort to dumb show.

小孩子们不会用手指拼字，但我可以唇读。

For people who are born with hearing impairments, it is more difficult to learn to lip-read.

为人民谁是天生听障，这是较为困难去学习唇读。

When the hand goes up communication goes down the listener cannot lip-read or hear what you are saying.

手举起来沟通就会减弱，听众就不能"唇读"或听出你在说什么。

Experiments also prove that the features of blocks DCT coefficients in lip region are efficacious to visual single channel lipreading system.

实验还证明了系统中分块的唇区DCT特征对的视觉单通道唇读系统是最有效的。

This method,on one hand extractes the most efficient low features for lipreading,on the other hand,selectes features reasonably to improve their distinguishability.With 42-dimensional two-level visual features can get 77.8% rate of lip movement contents recognition for speaker-dependent cases.

此方法一方面提取了唇读的最有效的低级语义特征，另一方面更加合理地选择利用了特征的有效可区分性，使得用42维二级视觉特征，对特定人的唇动内容识别正确率达到77.8%。

To solve the problem of detecting and tracking lip in lipreading, A new real time lip detectionmethod based on the discrepancy of s kin and lip on chrominance and R/G was proposed. First

摘要： 针对图像序列中唇读嘴唇实时检测跟踪问题，提出了一种利用肤色、唇色色度聚类特性，以及R/G 特性差异检测嘴唇的新方法。
