Recognizing human emotions from videos requires a deep understanding of the underlying multimodal sources, including images, audio, and text. Since the input data sources are highly variable across different modality combinations, leveraging multiple modalities often requires ad hoc fusion networks. To predict the emotional arousal of a person reacting to a given video clip we present ViPER, a multimodal architecture leveraging a modality-agnostic transformer-based model to combine video frames, audio recordings, and textual annotations. Specifically, it relies on a modality-agnostic late fusion network which makes ViPER easily adaptable to different modalities. The experiments carried out on the Hume-Reaction datasets of the MuSe-Reaction challenge confirm the effectiveness of the proposed approach.

Abstract
Recognizing human emotions from videos requires a deep understanding of the underlying multimodal sources, including images, audio, and text. Since the input data sources are highly variable across different modality combinations, leveraging multiple modalities often requires ad hoc fusion networks. To predict the emotional arousal of a person reacting to a given video clip we present ViPER, a multimodal architecture leveraging a modality-agnostic transformer-based model to combine video frames, audio recordings, and textual annotations. Specifically, it relies on a modality-agnostic late fusion network which makes ViPER easily adaptable to different modalities. The experiments carried out on the Hume-Reaction datasets of the MuSe-Reaction challenge confirm the effectiveness of the proposed approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
