Capturing Dynamics: The 4D Facial Expression Intensity Dataset

Zesheng Wang, Alexandre Bruckert, Pierre Lebreton et al. · 2026 · 10.1109/mipr70517.2026.00076

The estimation and analysis of facial expression intensity play a crucial role in affective communication and human-computer interaction. Previous research has primarily focused on detecting and estimating facial expression intensity from frame-level 2D representations. However, this limitation restricts a comprehensiv …

MoTop: Motion-Topological Model For Micro AU Detection

Huai-Qian Khor, Mengting Wei, Yante Li et al. · 2026

Facial micro-expressions are spontaneous, brief, and subtle facial movements that reveal suppressed emotions in high-stakes environments. In contrast to classic expression analysis, detecting action unit (AU) yields a finer representation of facial movements, serving as a preliminary step before defining expression cla …
