On Constrained Local Model Feature Normalization for Facial Expression Recognition [chapter]

Zhenglin Pan, Mihai Polceanu, Christine Lisetti
2016 Lecture Notes in Computer Science  
Real time user independent facial expression recognition is important for virtual agents but challenging.  ...  In this paper, we present a new approach that instead of using the traditional base face normalization on whole face shapes, performs normalization on the point cloud of each landmark.  ...  While tasks such as face recognition require differentiating between individuals based on facial features, facial expression recognition relies on variations of these facial features and on their dynamics  ...
