Automatic 3D Facial Expression Analysis in Videos [chapter]

Ya Chang, Marcelo Vieira, Matthew Turk, Luiz Velho
2005 Lecture Notes in Computer Science  
We first build a 3D expression database to learn the expression space of a human face. The real-time 3D video data were captured by a camera/projector scanning system.  ...  We introduce a novel framework for automatic 3D facial expression analysis in videos. The preliminary results were demonstrated by editing the facial expression with facial recognition.  ...  The ( b,s)-BCSL code provides an efficient camera/projector correspondence scheme. Parameter b is the number of colors and s is the number of patterns to be projected.  ...
