Researchers have developed new methods to improve facial expression understanding in videos using Vision Transformers (ViTs). One approach, MiRA, is a plug-in framework that redistributes attention to focus on subtle facial dynamics without adding trainable parameters, offering both an exact and an efficient approximation mode. Another method, FEDN, unifies facial expression spotting and recognition into a single end-to-end detection task, utilizing temporal attention modules across different scales to capture both fine-grained local dynamics and broader temporal context. Both approaches have demonstrated improved performance on facial expression recognition benchmarks. AI
