Summary

AbsoluteDegradation is a novel, physics-inspired pipeline and large-scale benchmark designed to address critical challenges in archival film restoration, specifically the absence of paired training data and standardized evaluation. Published on 2026-07-02, the modular pipeline synthesizes realistic film degradations by modeling the analog-to-digital process as a structured composition of artifact families, including signal-dependent grain, parametric scratches, and temporally coherent camera motion. This enables controlled generation of diverse degradation regimes. Complementing the pipeline, a new benchmark introduces a curated dataset of 81,576 high-resolution frames sourced from real archival footage, ensuring consistent evaluation under real-world conditions. Extensive experiments demonstrate that models trained using AbsoluteDegradation generalize more effectively to real-world footage, while the benchmark identifies systematic failure modes in current restoration methods. This work aims to establish a foundation for reproducible and domain-authentic evaluation.

Key takeaway

For computer vision engineers developing archival film restoration models, AbsoluteDegradation provides a critical resource. You should integrate this physics-inspired pipeline to generate more realistic synthetic training data, improving your model's generalization to real-world footage. Utilize the new 81,576-frame benchmark for consistent, domain-authentic evaluation, allowing you to identify and address systematic failure modes in your current methods. This framework offers a path to more robust and reproducible restoration solutions.
