About the content

This course provides an introduction to computer vision including fundamentals of image formation, camera imaging geometry, feature detection and matching, multiview geometry including stereo, motion estimation and tracking, and classification. We’ll develop basic methods for applications that include finding known models in images, depth recovery from stereo, camera calibration, image stabilization, automated alignment (e.g. panoramas), tracking, and action recognition. We focus less on the machine learning aspect of CV as that is really classification theory best learned in an ML course. The focus of the course is to develop the intuitions and mathematics of the methods in lecture, and then to learn about the difference between theory and practice in the problem sets. All algorithms work perfectly in the slides. But remember what [Yogi Berra]( said: In theory there is no difference between theory and practice. In practice there is. (Einstein said something similar but who knows more about real life?) In this course you do not, for the most part, apply high-level library functions but use low to mid level algorithms to analyze images and extract structural information.

  • Aaron Bobick - Aaron Bobick, PhD, joined Washington University in St. Louis as Dean of the School of Engineering & Applied Science and the James M. McKelvey Professor July 1, 2015. Prior to Washington University, he was a professor and founding chair of the School of Interactive Computing at the Georgia Institute of Technology, where he was a member of the faculty since 1999. He has B.Sc. degrees from MIT in Mathematics (1981) and Computer Science (1981) and a Ph.D. from MIT in Cognitive Science (1987). He joined the MIT Media Laboratory faculty in 1992 where he was a pioneer in the area of action recognition by computer vision. In 1999 Prof. Bobick moved to Georgia Tech where he became the Director of the GVU Center, an internationally known research center in computer vision, graphics, ubiquitous computing, and HCI. In 2005 the School of Interactive Computing was created with Prof. Bobick serving as the founding Chair. Prof. Bobick is both an IEEE Fellow and an ACM Distinguished Scientist. He has served as a senior area chair for most international computer vision conferences including serving as Program Chair of IEEE Conference on Computer Vision and Pattern Recognition. He has also served on the advisory board or boards of directors of a variety of surveillance-focused computer vision and medical imaging technology companies.

Georgia Institute of Technology

The Georgia Institute of Technology, also known as Georgia Tech or GT, is a co-educational public research university located in Atlanta, Georgia, USA. It is part of the wider University System of Georgia network. Georgia Tech has offices in Savannah (Georgia, USA), Metz (France), Athlone (Ireland), Shanghai (China), and Singapore.

Georgia Tech's reputation is built on its engineering and computer science programmes, which are among the best in the world5,6. The range of courses on offer is complemented by programmes in the sciences, architecture, humanities and management.




Udacity is a for-profit educational organization founded by Sebastian Thrun, David Stavens, and Mike Sokolsky offering massive open online courses (MOOCs). According to Thrun, the origin of the name Udacity comes from the company's desire to be "audacious for you, the student". While it originally focused on offering university-style courses, it now focuses more on vocational courses for professionals.
