Dr. Dan Levi

Staff Researcher
General Motors


I received my B.Sc. degree (with honor) in mathematics and computer science from the Tel-Aviv University, in 2000, and the M.Sc. and PhD degrees in applied mathematics and computer science at the Weizmann Institute, in 2004 and 2009 respectively. In the Weizmann Institute I conducted research in human and computer vision under the supervision of Professor Shimon Ullman. Since 2007 I have been conducting industrial computer vision research and development at several companies including General Motors and Elbit Systems, Israel.


Training Models for Road Scene Understanding with Automated Ground Truth


Collecting and labeling training data for vision-based road scene understanding is a major challenge. The most prominent approach is to use manual labeling, though it is clear that scalability of this approach is limited. More scalable alternatives are simulated data and cross-sensor label transfer. In this talk I will present automatically generated ground truth using one or more sensors, primarily dense Lidar. Specifically, I will present the benefits and challenges of this approach for road scene understanding tasks, including general and category-based obstacle detection, free space and curb detection.
