PSHuman is an innovative framework that utilizes multi-view diffusion models and explicit reconstruction techniques to reconstruct realistic 3D human models from a single image. Its significance lies in its ability to handle complex self-occlusion issues and avoid geometric distortions in the generated facial details. PSHuman achieves richly detailed new perspective generation while maintaining identity features by jointly modeling global body shapes and local facial characteristics with cross-scale diffusion models. Additionally, PSHuman enhances cross-view body shape consistency under different human postures using physical priors provided by parameterized models like SMPL-X. Key advantages of PSHuman include rich geometric details, high texture fidelity, and strong generalization capability.
