论文摘要
在本文中，讨论了一些用于将面部嘴唇定位的不同技术及其处理步骤进行比较。唇部定位是阅读嘴唇以从视频输入中提取视觉信息所需的基本步骤。这些技术可以应用于不对称的嘴唇上，还可以用可见的牙齿，舌头和嘴巴带有胡须。在唇读的过程中，通常使用以下步骤。它们最初是在视频输入的第一帧中定位的，然后使用最初步骤的产生像素点在以下帧中跟踪嘴唇，最后将跟踪的唇部模型转换为相应的匹配字母以提供视觉信息。从讨论的技术中也启动了一项新建议。当通信系统中缺乏或没有噪声的情况下，音频缺乏或没有噪声时，唇读对于自动语音识别很有用。人类的计算机通信还需要语音识别。
In this paper some of the different techniques used to localize the lips from the face are discussed and compared along with its processing steps. Lip localization is the basic step needed to read the lips for extracting visual information from the video input. The techniques could be applied on asymmetric lips and also on the mouth with visible teeth, tongue & mouth with moustache. In the process of Lip reading the following steps are generally used. They are, initially locating lips in the first frame of the video input, then tracking the lips in the following frames using the resulting pixel points of initial step and at last converting the tracked lip model to its corresponding matched letter to give the visual information. A new proposal is also initiated from the discussed techniques. The lip reading is useful in Automatic Speech Recognition when the audio is absent or present low with or without noise in the communication systems. Human Computer communication also will require speech recognition.
