Hi3DFace: High‐Realistic 3D Face Reconstruction From a Single Occluded Image

Abstract We propose Hi3DFace, a novel framework for simultaneous de‐occlusion and high‐fidelity 3D face reconstruction. To address real‐world occlusions, we construct a diverse facial dataset by simulating common obstructions and present TMANet, a transformer‐based multi‐scale attention network that effectively removes occlusions and restores clean face images. For the 3D face reconstruction stage, we propose a coarse‐medium‐fine self‐supervised scheme. In the coarse reconstruction pipeline, we adopt a face regression network to predict 3DMM coefficients for generating a smooth 3D face. In the medium‐scale reconstruction pipeline, we propose a novel depth displacement network, DDFTNet, to remove noise and restore rich details to the smooth 3D geometry. In the fine‐scale reconstruction pipeline, we design a GCN (graph convolutional network) refiner to enhance the fidelity of 3D textures. Additionally, a light‐aware network (LightNet) is proposed to distil lighting parameters, ensuring illumination consistency between reconstructed 3D faces and input images. Extensive experimental results demonstrate that the proposed Hi3DFace significantly outperforms state‐of‐the‐art reconstruction methods on four public datasets, and five constructed occlusion‐type datasets. Hi3DFace achieves robustness and effectiveness in removing occlusions and reconstructing 3D faces from real‐world occluded facial images.
