Descrição
Resumo:Recent advances in technology have allowed humans to interact with computers in ways previously unimaginable. Despite significant progress, a necessary element for natural interaction is still lacking: emotions. Emotions play an important role in human communication and interaction, allowing people to express themselves beyond the language domain. The purpose of this project is to develop a multimodal system to classify emotions using facial expressions and the voice taken from videos. For face emotion recognition, face images and optical flow frames are used to exploit spatial and temporal information of the videos. Regarding the voice, the model uses speech features extracted from the chunked audio signals to predict the emotion. The combination of the two biometrics with a score-level fusion achieves excellent performance on the RAVDESS and the BAUM-1 datasets. However, the results remark the importance of further investigating the preprocessing techniques applied in this work to "normalize" the datasets to a unified format to improve the cross-dataset performance.
