Attention-enhanced CNN-LSTM framework for real-time video-based emotion recognition
Emotion recognition from videos plays a vital role in enhancing interactive experiences across computer graphics and virtual reality (VR) applications. This paper presents EmotionViA, an attention-enhanced CNN-LSTM framework designed for real-time emotion recognition from facial expressions in videos. The framework integrates convolutional neural networks (CNNs) for spatial feature extraction and long short-term memory (LSTM) networks for capturing temporal dynamics, while an attention mechanism selectively emphasizes salient facial regions to improve classification accuracy. To further support research reproducibility, we introduce the EmotionViA dataset, encompassing diverse emotional expressions under varied conditions. Experimental results on EmotionViA, FER-2013, AffectNet, and RAF-DB demonstrate that our method surpasses state-of-the-art approaches in both accuracy and real-time performance. EmotionViA holds potential for immersive applications in education, entertainment, health care, and marketing. Our code is available at https://github.com/rizwanchouhan/emovid.

Emotion Classification
EmotionViA integrates Convolutional Neural Networks (CNNs) for robust spatial feature extraction, Long Short-Term Memory (LSTM) networks for capturing temporal dynamics, and an attention mechanism to selectively emphasize salient facial regions. This hybrid approach ensures comprehensive capture of emotional nuances.
Real-Time Processing Capabilities
The EmotionViA framework achieves a real-time performance of 42 frames per second (FPS) on an NVIDIA RTX 3080 GPU, surpassing the standard video frame rate of 30 FPS. This robust performance is maintained with a moderate computational complexity of 24.5 million parameters and 18.7 GFLOPs, ensuring suitability for live video streams and interactive applications.
Transforming Education with EmotionViA
EmotionViA offers profound potential in education by enabling adaptive learning environments. It allows teachers to monitor students' real-time emotional responses, tailoring instructional strategies to better engage learners and provide immediate feedback. For students with special needs, particularly those on the autism spectrum, EmotionViA can offer critical insights into their emotional states, facilitating customized support and a more inclusive classroom atmosphere.
| Feature | EmotionViA Dataset | Conventional Datasets |
|---|---|---|
| Source | Short video clips from movie scenes (natural/spontaneous expressions) | Static images, less temporal context |
| Temporal Dynamics | Preserves temporal continuity, captures rapid emotional transitions | Limited temporal diversity, frame-based |
| Subject Variability | Subject-independent protocol (110 unique subjects) | Often limited subject variability |
| Realism | Naturalistic, diverse emotional expressions | Conventional, sometimes posed expressions |
The introduction of the EmotionViA dataset addresses critical limitations of existing frame-based datasets by providing diverse, naturalistic emotional expressions with preserved temporal continuity, significantly enhancing model generalizability.
