About me
This is Haiwei LIN. I am currently pursuing my Ph.D. degree in the Graduate School of Informatics at Chiba University, under the supervision of Assoc. Prof. Shoko Imaizumi. My research focuses on visual privacy protection, exploring methods to generate visually uninformative images / videos that remain recognizable to AI models. These works are supported by JST BOOST.
