LD-RPS: Zero-Shot Unified Image Restoration via Latent Diffusion Recurrent Posterior Sampling
Huaqiu Li, Yong Wang†, Tongwen Huang, Hailang Huang, Haoqian Wang†, Xiangxiang Chu
Paper Code

- We propose a novel, dataset-free, and unified approach through recurrent posterior sampling utilizing a pretrained latent diffusion model. Our method incorporates a multimodal understanding model to provide semantic priors for the generative model under a task-blind condition.

Interpretable Unsupervised Joint Denoising and Enhancement for Real-World Low-Light Scenarios
Huaqiu Li, Xiaowan Hu, Haoqian Wang†
Openreview Paper Code

- We propose an interpretable, zero-reference joint denoising and low-light enhancement framework tailored for real-world scenarios. Our method derives a training strategy based on paired sub-images with varying illumination and noise levels, grounded in physical imaging principles and Retinex theory.

Prompt-SID: Learning Structural Representation Prompt via Latent Diffusion for Single-Image Denoising
Huaqiu Li*, Wang Zhang*, Xiaowan Hu, Tao Jiang, Zikang Chen, Haoqian Wang†
Paper Code

- In this paper, we introduce Prompt-SID, a prompt-learning-based single image denoising framework that emphasizes preserving structural details. This approach is trained in a self-supervised manner using downsampled image pairs.

Spatiotemporal Blind-Spot Network with Calibrated Flow Alignment for Self-Supervised Video Denoising
Chen, Zikang; Jiang, Tao; Hu, Xiaowan; Zhang, Wang; Li, Huaqiu; Wang, Haoqian†
Paper Code

- We explore the practicality of optical flow in the self-supervised setting and introduce a SpatioTemporal Blind-spot Network (STBN) for global frame feature utilization.

Measuring and Controlling the Spectral Bias in Self-Supervised Denoising
Wang Zhang*, Huaqiu Li*, Tao Jiang, Zikang Chen, Haoqian Wang†
Paper Code

- We introduce a Spectral Controlling network (SCNet) to optimize self-supervised denoising of paired noisy images. First, we propose a selection strategy to choose frequency band components for noisy images, accelerating the convergence speed of training.

MMGenBench: Fully Automatically Evaluating LMMs from the Text-to-Image Generation Perspective
Hailang Huang, Yong Wang, Zixuan Huang, Huaqiu Li, Tongwen Huang, Xiangxiang Chu, Richong Zhang†
Paper Code

- We propose the MMGenBench-Pipeline, a straightforward and fully automated evaluation pipeline. This involves generating textual descriptions from input images, using these descriptions to create auxiliary images via text-to-image generative models, and then comparing the original and generated images.
