• Abstract: This paper presents InceptionHuman, a prompt-to-NeRF framework that allows easy control via a combination of prompts in different modalities (e.g., text, poses, edge, segmentation map, etc) as inputs to generate photorealistic 3D humans. While many works have focused on generating 3D human models, they suffer one or more of the following: lack of distinctive features, unnatural shading/shadows, unnatural poses/clothes, limited views, etc. InceptionHuman achieves consistent 3D human generation within a progressively refined NeRF space with two novel modules, Iterative Pose-Aware Refinement (IPAR) and Progressive-Augmented Reconstruction (PAR). IPAR iteratively refines the diffusion-generated images and synthesizes high-quality 3D-aware views considering the close-pose RGB values. PAR employs a pretrained diffusion prior to augment the generated synthetic views and adds regularization for view-independent appearance. Overall, the synthesis of photorealistic novel views empowers the resulting 3D human NeRF from 360-degree perspectives. Extensive qualitative and quantitative experimental comparison show that our InceptionHuman models achieve state-of-the-art application quality.

  We propose HumanRef, a 3D human generation framework from a single-view input. To ensure the generated 3D model is photorealistic and consistent with the input image, HumanRef introduces a novel method called reference-guided score distillation sampling. Experimental results demonstrate that HumanRef outperforms state-of-the-art methods in generating 3D clothed humans.
