Fine-Grained 3D Facial Reconstruction for Micro-Expressions

ArXi:2603.07043v1 Announce Type: new Recent advances in 3D facial expression reconstruction have nstrated remarkable performance in capturing macro-expressions, yet the reconstruction of micro-expressions remains unexplored. This novel task is particularly challenging due to the subtle, transient, and low-intensity nature of micro-expressions, which complicate the extraction of stable and discriminative features essential for accurate reconstruction.
