Automatic Facial Expression Recognition
Jacob Whitehill, Marian Stewart Bartlett, Javier R. Movellan · Oxford University Press eBooks · 2013
In this chapter we define the problem space and describe the core components of automatic facial expression recognition systems. In particular, we discuss the most prominent methods of face segmentation, face registration, feature extraction, classification, and temporal integration. We then present several practical applications of expression recognition technology. Finally, we comment on the core future challenges to the field, including generalization to multiple poses and ethnicities, collection of better training data, evaluation infrastructure, and commercialization.
