Intell. Comput. imag. Lab. (ICL)'s research spans advanced medical imaging (CT, PET/SPECT reconstruction, motion correction, and quantitative imaging), pioneering generative AI and diffusion models (text-to-image/video generation, personalization, efficient adaptation), and robust computer vision and image restoration (super-resolution, semantic segmentation, denoising, and real-world visual enhancements), publishing our works in major medical imaging / signal processing journals as well as presenting them at major machine learning / computer vision conferences. ICL is at the Department of Electrical and Computer Engineering, Seoul National University and is led by Se Young Chun. ICL is also affiliated with the Interdisciplinary Program in Artificial Intelligence, Seoul National University.
