Think Before You Restore: Risk-Aware Manchu Manuscript Restoration with Stroke-Guided Attention

The paper introduces SAGE-Restore, a stroke-aware restoration framework for full-page blind restoration of historical Manchu manuscripts. It first predicts patch-level repair probabilities using appearance and stroke-structural cues, then refines these into pixel-level soft gates to selectively apply restoration candidates. The authors also propose a fidelity-aware evaluation protocol and report that SAGE-Restore achieves superior recovery and fidelity metrics compared to existing methods.

Beyond Pixel Reconstruction: Retrieval-Guided Glyph-Aware Restoration for Low-Resource Manchu Historical Documents

The paper introduces a retrieval-guided glyph-aware restoration framework for low-resource Manchu historical documents. Unlike traditional pixel-level reconstruction methods, it incorporates glyph-level structural knowledge by retrieving relevant glyph exemplars to guide the restoration process. Experiments show that this approach improves both image quality and glyph fidelity compared to existing methods.

ImIR: Image-Instruction Tuning for All-in-One Image Restoration

The paper introduces ImIR, a method that tunes a large pretrained image‑editing model for all‑in‑one image restoration by replacing text prompts with continuous image‑derived instructions. The approach uses a lightweight token mapper to shift the degraded image’s vision‑language embedding toward that of a clean image, enabling a single adapter to handle six restoration tasks in about three hours on one GPU. ImIR outperforms text conditioning in matched comparisons and supports task‑agnostic restoration without requiring a degradation label.

SkillIR: Evolving Scene-Aware Skills for Agentic Image Restoration

SkillIR is a skill-guided framework for agentic image restoration that represents restoration experience as degradation-centered action evidence rather than full tool-use trajectories. It consolidates context-dependent action outcomes into scene-aware restoration skills, guiding one bounded action at a time within a verified residual-state loop. Experiments on synthetic and real-world multi-degradation datasets show that SkillIR improves restoration quality and enables more reliable and effective tool use.

Loop-Mamba: A Loop Mamba with Degradation-Aware and Shared Memory for Old Photo Restoration

Loop‑Mamba is a lightweight, loop‑based state‑space framework designed for restoring old photographs that suffer from multiple degradations such as scratches, cracks, fading, blur, noise, and missing regions. It models restoration as progressive state evolution, using a Semantic‑Guided Degradation Estimator to predict local degradation maps and global scores, and a Shared Structural Memory Mamba to maintain a persistent restoration state across iterations. The method employs first‑order state recursion and a multi‑directional scanning strategy to reduce gradient dilution and computational overhead, and introduces the Old Photo Damage Recovery Score (ODRS) to evaluate both degradation recovery and structural reconstruction, achieving superior performance on the SynOld benchmark.
