Xin Li, Yeying Jin, Suhang Yao +95
This paper presents an overview of the NTIRE 2026 Second Challenge on Day and Night Raindrop Removal for Dual-Focused Images. Building upon the success of the first edition, this c…
RealDiffusion: Physics-informed Attention for Multi-character Storybook Generation
Qi Zhao, Jun Chen, Ivor Tsang +1
While modern diffusion models excel at generating diverse single images, extending this to sequential generation reveals a fundamental challenge: balancing narrative dynamism with…
UniBlendNet: Unified Global, Multi-Scale, and Region-Adaptive Modeling for Ambient Lighting Normalization
Jiatao Dai, Wei Dong, Han Zhou +2
Ambient Lighting Normalization (ALN) aims to restore images degraded by complex, spatially varying illumination conditions. Existing methods, such as IFBlend, leverage frequency-do…
RetinexDualV2: Physically-Grounded Dual Retinex for Generalized UHD Image Restoration
Mohab Kishawy, Jun Chen
We propose RetinexDualV2, a unified, physically grounded dual-branch framework for diverse Ultra-High-Definition (UHD) image restoration. Unlike generic models, our method employs…
