Ph.D. Thesis

I received my Ph.D. degree from the computer science department, Technion, Israel, in 2008. My supervisor was Prof. Michael Lindenbaum.

My Thesis mainly deals with different aspects of visual attention for computer vision systems, but also includes a psychophysical study performed in cooperation with Dr. Yaffa Yeshurun, the psychology department, the Haifa University.
