Sameh Khamis
I am a PhD student in computer science at the University of Maryland, working with professor Larry Davis. I received a MSc in computer science in 2010 from the University of Western Ontario, Canada under the supervision of professor Yuri Boykov.
News
- RPR 1.03 released (minor bug fix)

- A new talk series launched: Computer Vision Student Seminars
Research
I am interested broadly in computer vision, machine learning, combinatorial optimization, and mathematical programming. I am currently working on a probabilistic approach to high-level interpretation of images and videos.
My Master's thesis focused on submodular energy minimization and its application to multi-class image segmentation problems with contextual constraints.
Code
RegionPushRelabel (RPR) is a parallel out-of-core max-flow/min-cut algorithm for massive graphs with repeating structure. The algorithm extends the work on grid graphs described in Delong and Boykov, CVPR 2008. The code can be found here. Visit the computer vision lab at the University of Western Ontario for more details.
