AraMS-Restore restores degraded lines from historical Arabic manuscripts. A U-Net takes a damaged handwritten line and returns a readable one, trained on synthetic damage (tears, ink blots, erasure, bleed-through, worm holes) calibrated against real manuscript decay.

The contribution is the ablation between two objectives on the same generator: Level 1 optimizes visual fidelity (L1 + perceptual + optional PatchGAN), while Level 2 adds a frozen HATFormer OCR critic that reads the restored image and scores it against the true transcription — so gradients flow into the pixels that matter for reading. Both are evaluated on held-out manuscripts by CER before vs. after restoration, including on real damaged scans rather than only synthetic damage.
