Face Video Restoration (FVR) aims to recover high-fidelity facial videos from degraded input while preserving identity and semantic consistency across frames. Existing methods often struggle to simultaneously address identity shift, viewpoint-entangled guidance, and perceptual realism.
We propose TIGER, a structured tri-prior fusion framework that tames Identity, Geometry, and gEnerative pRiors for high-quality FVR. TIGER anchors identity with subject-discriminative embeddings, lifts reference cues into a disentangled 3D geometry prior, and harnesses a video generative prior through one-step rectified flow.
A progressive three-stage training strategy refines structural fidelity, textural reconstruction, and distribution-level realism. Extensive experiments demonstrate state-of-the-art identity fidelity and temporal stability with efficient, identity-consistent face video restoration.
A tri-prior framework for identity-consistent, geometry-aware, and realistic restoration.
Reference identity embeddings are injected into the latent backbone to anchor subject-discriminative facial traits under severe degradation.
2D reference cues are lifted into a 3D parameter space and fused with frame motion to provide temporally consistent structure.
A one-step rectified-flow formulation transports degraded latents to the high-fidelity manifold while preserving photorealistic detail.
