---|---|---|
Emotion recognition in the wild is a very challenging task. In this paper, we investigate a variety of different multimodal features (acoustic and visual) from video clips to evaluate their discriminative abilities in human emotion analysis. For each clip, we extract MSDF BoW, LBP-TOP, PHOG, LPQ-TOP and Audio features. We train different classifiers for every type of feature on the AFEW dataset from the ICMI 2014 EmotiW Challenge, and we propose a novel hierarchical classification framework, which combines the feature-level and decision-level fusion strategy for all of the extracted multimodal features. The final achievement we gain on the AFEW test set is 47.17 %, which is considerably better than the best baseline recognition rate of 33.7 %. Among all of the teams participating in the ICMI 2014 EmotiW challenge, our recognition performance won the first runner-up award. Furthermore, we test our method on FERA and CK datasets, the experimental results also show good performance. |
