Chul Lee–이철

I am an Associate Professor with the Division of AI Software Convergence, Dongguk University, Seoul, Korea. I received the B.S., M.S., and Ph.D. degrees all in the School of Electrical Engineering from Korea University, Seoul, Korea, in 2003, 2008, and 2013, respectively. From 2002 to 2006, I was with Biospace Inc., where I was involved in the development of medical equipment. From 2013 to 2014, I was a Postdoctoral Scholar with the Department of Electrical Engineering, The Pennsylvania State University, University Park, PA, USA. From 2014 to 2015, I was a Research Scientist with the Department of Electrical and Electronic Engineering, The University of Hong Kong, Hong Kong. From 2015 to 2019, I was an Assistant Professor in the Department of Computer Engineering, Pukyong National University, Busan, Korea. My research interests are image restoration, power-constrained image/video processing, and high dynamic range imaging.
