I am a Phd student at the PCALab of Nanjing University of Science and Technology, where I'm fortunate to be advised by Prof. Jian Yang and co-advised by Prof. Jun Li. Prior to joining NJUST, I obtained my M.S degree in 2019 from Wenzhou University, advised by Prof. Zhengzhou Tang. Email / GitHub / Google Scholar / WeChat |

My research is focused on computer vision and image processing. I’m particularly interested in image restoration (e.g., real-world dehazing and depth estimation). Representative papers are highlighted. |

We propose a novel nighttime image enhancement framework using daytime-mixed misaligned supervision. It aims to couple information between non-aligned daytime and nighttime image pairs.
Specifically, our framework consists of a simple yet effective daytime-mixed supervised learning phase and a Retinex-based reconstruction phase.

LP-Net uses a multi-scale, progressive depth completion method via Laplacian Pyramid, starting with global scene context and refining local details with selective filtering.
It achieves SOTA on indoor/outdoor datasets, is computationally efficient, and leads the KITTI leaderboard among peer-reviewed methods at submission.

We propose a novel depth-centric learning framework that combines the atmospheric scattering model(ASM) model with the brightness consistency constraint (BCC) constraint.
The core idea is to use a shared depth estimation network for both ASM and BCC.

We propose a novel Structure Guided Dehazing Network (SGDN) that utilizes the superior structural properties of YCbCr features over RGB.
Additionally, we introduce the Real-World Well-Aligned Haze (RW2AH) dataset, featuring diverse scenes from various geographical and climatic conditions.

DCDepth uses discrete cosine transformation on depth patches to estimate frequency coefficients, capturing local depth correlations.
It separates depth into low-frequency (global structure) and high-frequency (details) components, predicting global context first and refining details progressively.

We present an innovative video dehazing framework for real-world driving scenarios, addressing temporal and spatial misalignment
challenges with non-aligned hazy/clear video pairs and a reference frame matching module.

Given an image or video captured in a real foggy scene, our model is capable of restoring the corresponding clear scene image or video.
Moreover, training our model does not require fully aligned ground truth (GT), which helps us collect real hazy scene data.
