OneRestore: A Universal Restoration Framework for Composite Degradation
This addresses the limitation of existing methods that only handle isolated degradations, offering a more practical solution for real-world imaging applications.
The paper tackles the problem of restoring images with multiple simultaneous degradations (e.g., low light, haze, rain, snow) by proposing OneRestore, a transformer-based framework that adaptively handles composite scenarios, achieving state-of-the-art results on synthetic and real-world datasets.
In real-world scenarios, image impairments often manifest as composite degradations, presenting a complex interplay of elements such as low light, haze, rain, and snow. Despite this reality, existing restoration methods typically target isolated degradation types, thereby falling short in environments where multiple degrading factors coexist. To bridge this gap, our study proposes a versatile imaging model that consolidates four physical corruption paradigms to accurately represent complex, composite degradation scenarios. In this context, we propose OneRestore, a novel transformer-based framework designed for adaptive, controllable scene restoration. The proposed framework leverages a unique cross-attention mechanism, merging degraded scene descriptors with image features, allowing for nuanced restoration. Our model allows versatile input scene descriptors, ranging from manual text embeddings to automatic extractions based on visual attributes. Our methodology is further enhanced through a composite degradation restoration loss, using extra degraded images as negative samples to fortify model constraints. Comparative results on synthetic and real-world datasets demonstrate OneRestore as a superior solution, significantly advancing the state-of-the-art in addressing complex, composite degradations.
