Abstract :
This research discusses the problems of lips localization and feature point detection which have gained much attention in applications such as lip-reading, visual-assisted speech recognition, audio/video synchronization, etc. Our method is primarily based upon morphological processing of time-difference images which highlight lip motions. Experiments show that acceptable results can be obtained
