Efficient AI Low-level Vision

I am a Ph.D. student in Electrical Engineering at Korea University, advised by Prof. Seung-Won Jung. My research focuses on efficient AI and low-level vision, with an emphasis on inference-efficient and hardware-aware models, including logic-based neural networks, image restoration, and camera ISP.

Research Interests

01

Efficient AI

Inference-efficient models, data-efficient learning, hardware-aware models, and logic-based neural networks.

02

Low-level Vision

Image restoration and camera ISP, with an emphasis on computationally efficient image processing.

Overcoming Kernel Redundancy for
Scaling Logic Gate Networks

Can logic gate networks turn width into effective capacity?

Observation

A function-aware tree edit distance reveals increasing kernel redundancy with width, especially at the first gate level.

Idea

We propose DLK for input-dependent routing across logic kernel groups, and EDLK to focus routing on the highly redundant first gate level.

Outcome

Turns additional width into effective capacity, improving accuracy and parameter efficiency.

IM-LUT: Interpolation Mixing Look-Up Tables for Image Super-Resolution

Can LUTs alone enable arbitrary-scale super-resolution?

Idea

Learn interpolation mixing weights and convert them into LUTs for efficient arbitrary-scale super-resolution.

Outcome

Enables continuous-scale super-resolution while retaining efficient LUT-based inference.

FDCNet: Feature Drift Compensation Network for Class-Incremental Weakly Supervised Object Localization

Can weakly supervised localization learn new classes without forgetting previously learned localization knowledge?

Idea

Compensate feature drift caused by class-incremental learning to preserve localization capability across sequential tasks.

Outcome

Maintains localization knowledge while progressively learning new object classes.
