Thresholded Cross-Attention for Reliable Intensity-Chromaticity Fusion in Low-Light Image Enhancement
Yanyi Wu, Xu Zhang, Junkai Chen +6
Low-Light Image Enhancement (LLIE) requires a careful balance among noise suppression, color fidelity, and efficiency. Recent HVI-based methods alleviate color entanglement by deco…

Distortion-Aware Loop Filtering of Intra 360^o Video Coding with Equirectangular Projection
Pingping Zhang, Xu Wang, Linwei Zhu +3
In this paper, we propose a distortion-aware loop filtering model to improve the performance of intra coding for 360 videos projected via equirectangular projection (ERP) forma…
