New RASR method automates image restoration using retrieval

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Retrieval-Augmented Super Resolution (RASR), a novel approach to image restoration that addresses the limitations of existing reference-based methods. Unlike previous techniques requiring manually paired images, RASR automatically retrieves relevant high-resolution reference images from a database, making it more practical for real-world applications like enhancing mobile photos. The team also developed RASRNet, a baseline model that combines a semantic retriever with a diffusion-based generator, and created RASR-Flickr30, the first benchmark dataset for this task. AI

IMPACT This research could lead to more practical and effective image enhancement tools for consumer devices.

    RASR: Retrieval-Augmented Super Resolution for Practical Reference-based Image Restoration

    arXiv:2508.09449v2 Announce Type: replace Abstract: Reference-based Super Resolution (RefSR) improves upon Single Image Super Resolution (SISR) by leveraging high-quality reference images to enhance texture fidelity and visual realism. However, a critical limitation of existing R…
