Pathology-Aware Adaptive Watermarking for Text-Driven Medical Image Synthesis
Chanyoung Kim,
Dayun Ju,
Jinyeong Kim,
Woojung Han,
Roberto Alcover-Couso,
Seong Jae Hwang
arXiv, 2025
We develop the first watermarking method specifically designed for text-driven medical image synthesis, where regions of interest are automatically preserved from the watermarking process by generating an adaptive attention map.

Your Large Vision-Language Model Only Needs A Few Attention Heads For Visual Grounding
Seil Kang,
Jinyeong Kim,
Junhyeok Kim,
Seong Jae Hwang
CVPR, 2025
Our work discovers that a few attention heads in frozen LVLMs demonstrate strong visual grounding capabilities. These "localization heads" immediately enable training-free visual grounding, achieving performance comparable to fine-tuning approaches while providing better interpretability.

See What You Are Told: Visual Attention Sink in Large Multimodal Models
Seil Kang*,
Jinyeong Kim*,
Junhyeok Kim,
Seong Jae Hwang
ICLR, 2025
Large multimodal models consistently see irrelevant parts of the input. Our work demystifies this phenomenon, dubbed "visual attention sink," and proposes a simple mitigation strategy.
