Title
Framework for combination aware AU intensity recognition
Abstract
We present a framework for combination aware AU intensity recognition. It includes a feature extraction approach that can handle small head movements which does not require face alignment. A three layered structure is used for the AU classification. The first layer is dedicated to independent AU recognition, and the second layer incorporates AU combination knowledge. At a third layer, AU dynamics are handled based on variable duration semi-Markov model. The first two layers are modeled using extreme learning machines (ELMs). ELMs have equal performance to support vector machines but are computationally more efficient, and can handle multi-class classification directly. Moreover, they include feature selection via manifold regularization. We show that the proposed layered classification scheme can improve results by considering AU combinations as well as intensity recognition.
