This paper presents a method of tracking points on a speaking face and the reconstruction of a face model from speaking descriptive vectors followed. After capturing a video of a talking face using a CCD camera, his facial expression changes in a video sequences. The essencial of this work is to track the feature points on the face using the Lucas-Kanade method, then use descriptive vectors up to be exploited for the reconstruction of a model of speaking face. The tracking method used is based on the theorem of Lucas-Kanade and facial reconstruction based on the method of delaunay triangulation.
