Abstract: In order to overcome the problems of poor recognition accuracy and low recognition accuracy in traditional character emotion recognition algorithms, this paper proposes a small sample video character emotion recognition algorithm based on multimodal feature fusion, aiming to overcome the problems of low accuracy and poor precision in traditional algorithms. The steps of this algorithm include extracting facial image scene features and expression features from small sample videos, using GloVe technology to extract text features, and obtaining character speech features through filter banks. Subsequently, a bidirectional LSTM model was used to fuse multimodal features, and emotions were classified using fully connected layers and softmax functions. The experimental results show that the method achieves an emotion recognition accuracy of up to 98.6%, with a recognition rate of 64% for happy emotions and 62% for neutral emotions.
