Prof. Ofer Hadar
About me

Prof. Ofer Hadar (M’97) received the BSc, the MSc (cum laude) and the PhD degrees from the Ben-Gurion University of the Negev, Israel, in 1990, 1992, and 1997, respectively, all in electrical and computer engineering. The prestigious Clore Fellowship supported his PhD studies. His PhD dissertation dealt with the effects of vibrations and motion on image quality and target acquisition.

From August 1996 to February 1997, he was with CREOL at Central Florida University, Orlando, FL, as a research visiting scientist, working on angular dependence of sampling MTF and over-sampling MTF. From October 1997 to March 1999, he was a post-doctoral fellow in the Department of Computer Science at the Technion-Israel Institute of Technology, Haifa. In 1999 Prof.

Hadar joined the Communication Systems Engineering Department at Ben-Gurion University of the Negev. Currently, he is an Associate Professor and the head of the department. His research interests include image compression, advanced video coding, H.264, SVC, packet video, transmission of video over IP networks, and image processing.

 Since 2011, Prof. Hadar is an Associate Editor of the optical Engineering journal. Prof. Hadar also works as a consultant of various Hi-Tech companies in Israel, and is a Senior member of IEEE and SPIE.
