Multimodal Local-Global Attention Network for Affective Video Content Analysis

With the rapid development of video distribution and broadcasting, affective video content analysis has attracted a lot of research and development activities recently. Predicting emotional responses of movie audiences is a challenging task in affective computing, since the induced emotions can be considered relatively subjective. In this article, we propose a multimodal local-global attention network (MMLGAN) for affective video content analysis. Inspired by the multimodal integration effect, we extend the attention mechanism to multi-level fusion and design a multimodal fusion unit to obtain a global representation of affective video. The multimodal fusion unit selects key parts from multimodal local streams in the local attention stage and captures the information distribution across time in the global attention stage. Experiments on the LIRIS-ACCEDE dataset, the MediaEval 2015 and 2016 datasets, the FilmStim dataset, the DEAP dataset and the VideoEmotion dataset demonstrate the effectiveness of our approach when compared with the state-of-the-art methods.
