Alexei A. Efros

from Wikipedia, the free encyclopedia

Alexei A. Efros (born April 9, 1975 in Saint Petersburg ) is an American computer scientist and professor at the University of California, Berkeley .

Efros studied computer science at the University of Utah with a bachelor's degree in 1997 and at the University of California, Berkeley , with a master's degree in 1999. He received his doctorate in 2003 from Jitendra Malik in Berkeley (Data-driven Approaches for Texture and Motion). As a post-doctoral student , he was in the Robotics Research Group at Oxford University. In 2004 he became Assistant Professor and 2010 Associate Professor at Carnegie Mellon University (Robotics Institute and Computer Science Faculty) and Associate Professor in 2013 and Professor at the University of California, Berkeley in 2017.

In 2009 he was a Guggenheim Fellow at the École normal supérieure (Paris) (WILLOW Laboratory).

In 1999, together with Thomas K. Leung, he published a paper on texture synthesis with non-parametric modeling ( image growing ), which simplified it considerably and had a revolutionary effect in this area. His 2008 work with James Hays was also very influential. Images were completed by algorithms that scanned millions of similar images on the Internet or from extensive databases. This was applied many times afterwards. He later developed image transformation algorithms with deep learning to color black and white photos, to filter out typical characteristics of a city from numerous photos (essay What makes Paris look like Paris? ) Or to filter out time-bound style elements from portraits in high school yearbooks.

In 2016 he received the ACM Prize in Computing (ACM Infosys Award) for a groundbreaking data-driven approach to computer graphics and computer vision (laudation).
