DNF: Decouple and Feedback Network for Seeing in the Dark

CVPR 2023highlight

The exclusive properties of RAW data have shown great potential for low-light image enhancement. Nevertheless, the performance is bottlenecked by the inherent limitations of existing architectures in both single-stage and multi-stage methods. Mixed mapping across two different domains, noise-to-clea…

RIDCP: Revitalizing Real Image Dehazing via High-Quality Codebook Priors

CVPR 2023poster

Existing dehazing approaches struggle to process real-world hazy images owing to the lack of paired real data and robust priors. In this work, we present a new paradigm for real image dehazing from the perspectives of synthesizing more realistic hazy data and introducing more robust priors into the…

Underwater Ranker: Learn Which Is Better and How to Be Better

AAAI 2023technical

In this paper, we present a ranking-based underwater image quality assessment (UIQA) method, abbreviated as URanker. The URanker is built on the efficient conv-attentional image Transformer. In terms of underwater images, we specially devise (1) the histogram prior that embeds the color distribution…
