The Artificial Intelligence (AI) community is abuzz with excitement over the recent emergence of Large Language Models (LLMs)! These powerful models have demonstrated remarkable applications across a variety of industries, from Natural Language Processing and Natural Language Generation to Computer Vision and beyond. However, despite the considerable advances in computer vision and diffusion models, the challenge of generating high-fidelity, coherent new perspectives with limited input remains.
This is where the team of researchers from ByteDance is revolutionizing the AI landscape with their new DiffPortrait3D model. DiffPortrait3D is a unique, conditional diffusion model that enables the creation of photo-realistic, 3D-consistent views from a single in-the-wild portrait. This zero-shot model guarantees a high degree of realism, preserving the subject’s identity and expressions while producing facial details from new camera angles.
At the core of DiffPortrait3D is a generative prior from 2D diffusion models, which act as the model’s rendering framework. DiffPortrait3D also features a disentangled attentive control mechanism that controls appearance and camera posture, as well as a special conditional control module that analyses a condition image of a subject shot from the same angle in order to interpret the camera attitude. To maintain visual consistency, the model is also equipped with a trainable cross-view attention module and a 3D-aware noise-generating mechanism.
The team has evaluated and accessed the performance of DiffPortrait3D on multi-view and in-the-wild benchmarks, exhibiting both qualitatively and numerically state-of-the-art results. This innovative approach has successfully tackled the challenges of single-image 3D portrait synthesis by producing realistic, high-quality facial reconstructions under a variety of artistic styles and settings.
