Project Paper Code Model

- We introduce EchoStyle, a scalable text-driven framework for high-fidelity video stylization of arbitrary-length videos. It combines a video-to-video architecture, the reverse-synthesized V-Style20k dataset, and init-follow-mode sliding-window inference to preserve style, motion, and temporal consistency.

Self-supervised Dynamic Heterogeneous Degradation Modeling for Unified Zero-Shot Image Restoration

CVF arXiv

- We propose UP-ZeroIR, a self-supervised unified physical zero-shot restoration framework that models heterogeneous degradations as a homogeneous latent-space distribution. A dynamic quality-refinement strategy adaptively adjusts the diffusion trajectory for robust restoration across both single and mixed degradations.

- We propose a dataset-free, task-blind unified image restoration approach based on recurrent posterior sampling with a pretrained latent diffusion model and semantic priors from a multimodal understanding model.

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

- Prompt-SID is a self-supervised single-image denoising framework that preserves structural details by learning a latent structural representation from the noisy image; “prompt” here does not mean a natural-language prompt.

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 first 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, to accelerate the convergence speed of training.
