DART: A Degradation-Aware Recurrent Transformer for Archival Film Restoration

Summary

DART, a degradation-aware recurrent transformer, addresses the challenging problem of archival film restoration where historical footage contains compound degradations like scratches, dust, blur, noise, flicker, and photometric aging, and clean reference videos are unavailable. Unlike existing methods that implicitly handle degradations, DART explicitly predicts and propagates a soft defect mask through time. This mask guides temporal fusion and conditions the restoration network on both damage location and severity, making the process aware of film artifacts. Experiments on real archival benchmarks demonstrate that DART improves no-reference perceptual quality over prior architectures, remaining compact and efficient while producing cleaner, more temporally consistent restorations of structured film damage.

Key takeaway

For Computer Vision Engineers tackling archival film restoration, DART's explicit degradation-aware approach offers a significant improvement over implicit methods. If your projects involve restoring historical footage with complex, compound degradations, consider implementing or adapting DART's strategy of predicting and propagating defect masks. This can lead to cleaner, more temporally consistent results and enhanced perceptual quality in your restored videos.
