Sameh Khamis

I am a PhD student in computer science at the University of Maryland working with Larry Davis. I am also a member of the Computer Vision Laboratory (CVL) and the Institute for Advanced Computer Studies (UMIACS). I received a MSc in computer science in 2010 from the University of Western Ontario, Canada under the supervision of Yuri Boykov.

I am interested in aspects of discrete optimization, graphical models, and statistical learning applied to high-level vision problems. I have worked on:

• network flow for action recognition and identity maintenance
• parallelized limited-memory push-relabel for regular graphs
• graph cut-based semantic image segmentation with contextual constraints
