摘　　要：唇形轮廓的准确提取是唇形合成的基础。实现了基于Matlab的唇形参数提取平台,平台实现的主要功能包括:文件读取,关键点标记,文件播放及显示,参数提取及数据存储。考虑到边缘检测的局限性,平台采用手动标记的方法标记关键点,得到了较理想的唇形曲线及唇形人脸动画参数(FAP)。实验证明,该方法简单、有效。Accurate extraction for lip contour parameters is the base of lip synthesis. This paper realized the platform used for lip contour parameters based on Matlab. The main functions include text reading, key points labeling, file displaying, parameters extracting and data storing. Considering the limitations of border detection, the platform adopted artificial labeling method to make sure the places where key points exist to gain the more satisfied lip contour and lip Facial Animation Parameter （FAP）. The experiment has proved that this method is easy and efficient.
