Brian Clipp

Staff R&D Engineer

Dr. Clipp is a Staff Research and Development Engineer at Kitware. He joined the company in 2017.  Prior to joining Kitware, Dr. Clipp spent four years at URC Ventures, Inc., a startup company that focuses on commercial applications of three-dimensional (3D) reconstruction from imagery. There, he led a team of scientists and software developers to make a system for measuring stockpiles of material from ground-based (iPhone collected) and aerial (unmanned aerial vehicle and manned aircraft) imagery. The system has measured hundreds of millions of dollars of inventory for more than one hundred of the top aggregates, landscape materials, and pulp and paper processors in the world.  Dr. Clipp holds U.S. patent number 9,495,764 for his work on stockpile measurement.

Before joining URC Ventures, Inc., Dr. Clipp worked on the Defense Advanced Research Projects Agency (DARPA) ULTRA-Vis program at Applied Research Associates, Inc. This program focused on making a soldier-work, outdoor augmented reality system to improve the situational awareness of joint terminal attack controllers (JTACs).  As part of the program, Dr. Clipp co-developed algorithms to track the system wearer’s head motion from imagery, fusing computer vision with inertial sensor data.

As an undergraduate at Clemson University, Dr. Clipp completed honors research related to ad hoc wireless radio network transmission scheduling algorithms. He graduated magna cum laude in 2004 with a B.S. in computer engineering and a minor in mathematics.

Prior to beginning his graduate studies, Dr. Clipp spent a year as a civilian employee of the Naval Surface Warfare Center in Dahlgren, Virginia. Through his work as a systems engineer and a programmer, he made contributions to aircraft carrier design and to the Tomahawk Cruise Missile program.

Dr. Clipp received his M.S. in 2008 and his Ph.D. in 2010 from the University of North Carolina at Chapel Hill, where he was co-advised by Marc Pollefeys and Jan-Michael Frahm. Dr. Clipp’s doctoral thesis was on real-time 3D reconstruction from imagery.

Dr. Clipp has published eighteen articles in peer-reviewed, international computer vision and robotics conferences proceedings and journals. He regularly serves on program committees for top computer vision and robotics conferences such as the Conference on Computer Vision and Pattern Recognition (CVPR), the European Conference on Computer Vision (ECCV), the International Conference on Computer Vision (ICCV), and the IEEE Winter Conference on Applications of Computer Vision (WACV).
