It can be combined with other background restoration tools (like Real-ESRGAN) for a full-image enhancement. The model is available via the ⁠official GPEN

This specific model file represents one of the most powerful tools available for turning blurry, pixelated, or degraded faces into crystal-clear, high-resolution portraits. : Revitalizing blurry or grainy family historical photos

: Revitalizing blurry or grainy family historical photos into sharp, modern resolutions.

| Dataset | Size | Content | |---------|------|---------| | (official StyleGAN2 pre‑training) | 70 k high‑quality portraits | Balanced gender/ethnicity, diverse ages, backgrounds. | | Synthetic Degradation Pipeline (used for BFR) | N/A (on‑the‑fly) | Randomly sampled combinations of: • Down‑sampling factors (2‑× to 16‑×) • Gaussian blur (σ = 0‑3) • Motion blur (kernel lengths up to 25 px) • JPEG compression (Q = 10‑100) • Additive Gaussian noise (σ = 0‑25) • Random color shift (γ, contrast). | | Real‑World BFR Test Set (e.g., CelebA‑HQ degraded, LFW‑BFR) | 5 k images | For evaluation only, not used in training. |
