郭园方
Ph.D. & Assistant Professor
I received my B.S. and Ph.D. degrees from the Hong Kong University of Science and Technology, Hong Kong, in 2009 and 2015, respectively. Then, I served as an Assistant Professor with the State Key Laboratory of Information Security, Institute of Information Engineering, Chinese Academy of Sciences for three years. I am currently an Assistant Professor with the Laboratory of Intelligent Recognition and Image Processing, School of Computer Science and Engineering, Beihang University, Beijing, China. My research interests include image/video watermarking, data hiding, forensics, compression, restoration, and enhancement.
