Active shape lip modeling
Islam Shdaifat, Rolf‐Rainer Grigat, Detlev Langmann · 2004
We present a model for the lips using the active shape model (ASM) based on Bezier curves which can capture the dynamics of the lips efficiently. The curves are defined only by a few points that can be used as visual speech features. Using some measured feature points, we can recover the full model of the lips especially for those features which are difficult to be detected. Accurate detection of features of the lips is implemented using multiple independent feature templates.
