Abstract

Video-based Emotion recognition is rather challenging than vision task. It needs to model spatial information of each image frame as well as the temporal contextual correlations among sequential frames. For this purpose, we propose hierarchical deep network architecture to extract high-level spatial temporal features. Two classic neural networks, Convolutional neural network (CNN) and Bi-directional recurrent neural network (BRNN) are employed to capture facial textural characteristics in spatial domain and dynamic emotion changes in temporal domain. We endeavor to coordinate the two networks by optimizing each of them to boost the performance of the emotion recognition as well as to achieve greater accuracy as compared with baselines.
