π¨βπ About Me
I'm a Ph.D. student in Computer Science at Hanyang University, South Korea, where I am fortunate to be advised by Prof. Tae Hyun Kim.
My research focuses on developing reliable and efficient restoration systems for real-world images and videos.
Broadly, my work lies at the intersection of computer vision, machine learning, and generative modeling.
I design both dataset synthesis frameworks and restoration models for tasks such as video stabilization, image denoising, and super-resolution.
A key emphasis of my research is ensuring robustness under practical constraints, including test-time adaptation, continuous degradations, diverse unseen noise patterns.

Continuous Degradation Modeling via Latent Flow Matching for Real-World Super-Resolution
Hyeonjae Kim*, Dongjin Kim*, Eugene Jin, Tae Hyun Kim†
tl;dr: DegFlow learns a continuous real-world degradation manifold from sparse HRβLR pairs and uses it to generate realistic LR images at any scale, enabling stronger fixed-scale and arbitrary-scale SR models.
