I received the B.S. degree in Electronic Engineering from National Taiwan Institute of Technology, Taiwan, in 1989. In 1995, I earned the M.S. degree from the Department of Electrical Engineering of Tennessee Technological University, USA. Then I obtained my Ph.D. degree in Electrical Engineering from the University of Texas at Arlington, USA, in 1997. Currently, I am an associate professor at Department of Computer Science and Information Engineering in Chaoyang University of Technology, Taiwan. Since 1998, I have developed several grey models and other schemes applied to image, video, and speech signal processing. Those studies have been published journals and conferences. Currently, my research interests are on image restoration, image enhancement, image enlargement, error concealment, and image/video coding.
