M3D-Stereo supplies 7904 aligned stereo pairs across four multi-degradation scenarios with six progressive levels and pixel-consistent ground truths to benchmark image restoration and stereo matching.
Pre-trained diffusion models inherently support image restoration that can be unlocked by optimizing prompt embeddings at the text encoder output using a diffusion bridge formulation, achieving competitive results on models like WAN and FLUX without fine-tuning.
IQPIR uses NR-IQA-derived quality scores to condition a Transformer and dual-branch codebook for perceptually superior real-world image restoration.
SIMI is an unsupervised low-light image enhancement network using bit-plane decomposition to mine self-information, reported to reach state-of-the-art performance on standard benchmarks.
pHVI-ISPNet achieves state-of-the-art perceptual quality in night photography rendering by combining HVI color space with wavelet feature propagation, sample-adaptive losses, and distribution-based color constancy on the NTIRE 2025 NPR dataset.
Introduces LSTR and ESTR low-light text datasets and shows joint LLIE-OCR training outperforms standalone models.
FDINR decomposes RGB-NIR pairs into frequency components via wavelets and employs dual-branch INR with cross-modal supervision and adaptive uncertainty loss to restore low-light images while enabling arbitrary-resolution output.
RHVI-FDD hierarchically decouples luminance-chrominance and then frequency components in low-light images to correct color, suppress noise, and preserve details better than prior methods.
E-VLA integrates event streams directly into VLA models via lightweight fusion, raising Pick-Place success from 0% to 60-90% at 20 lux and from 0% to 20-25% under severe motion blur.
Stochastic image enhancement methods are shown to be variants of a shared SDE differing in drift, diffusion, terminal distributions and boundary conditions, with controlled experiments revealing no single dominant family and a new modular library released.
SmartPhotoCrafter performs automatic photographic image editing by coupling an Image Critic module that identifies deficiencies with a Photographic Artist module that generates edits, trained via multi-stage pretraining, reasoning supervision, and reinforcement learning.
NAKA-GS combines bionics-inspired Naka chroma correction with progressive point pruning to boost restoration quality and efficiency in low-light 3D Gaussian Splatting.
A deep learning method with an enhanced physical degradation model incorporating anisotropic light spread and hidden skyglow, trained via generative models and synthetic-real coupling, removes light pollution from night cityscape images more effectively than prior restoration techniques.
