Fresco++: Frequency-Guided and Canonical-Consistent Optimization for Fine-Grained Head Avatar Modeling

Read the original on arXiv Computer Vision →

Fresco++ is a unified optimization framework for fine‑grained, view‑consistent head avatar reconstruction. It uses a frequency‑guided curriculum that first stabilizes low‑frequency structures before adding high‑frequency constraints, and a Canonical Group Consensus that links local observations across viewpoints to enforce cross‑view consistency. The method incorporates geometric and visibility screening and aggregates multi‑view evidence in feature space, achieving stable optimization from coarse to fine details without extra rendering of auxiliary views.

OMEGA-Avatar: One-shot Modeling of 360{\deg} Gaussian Avatars

OMEGA-Avatar is a feed‑forward framework that creates a 360° complete, animatable 3D Gaussian head from a single image. It introduces a semantic‑aware mesh deformation module to improve hair modeling while preserving topology, and a multi‑view feature splatting module that builds a shared canonical UV representation for consistent, high‑frequency detail across all viewpoints. Experiments show it outperforms existing baselines in full‑head completeness and identity preservation.

GHARP: Real-time Gaussian Head Animation from Large-scale Reconstruction Prior

GHARP is a two‑stage method that animates 3D human heads in real time using a large‑scale reconstruction prior. The first offline identity stage builds a compact Gaussian representation of a subject’s geometry and appearance, while the lightweight runtime animation stage predicts expression‑dependent residuals in a semantically structured latent space. A body alignment network further refines the animation by aligning body pose and clothing, enabling state‑of‑the‑art quality on the Ava‑256 benchmark with significantly faster performance and fewer Gaussians.
