UAV control is a challenging research topic with significantly growing needs. I initiated and led a vision-based UAV control group at UC Berkeley. Our group successfully demonstrated the first vision-based UAV control system (automated road following system) which does not require any artificial markings. I introduced algorithms to detect roads and rivers in realtime with a semisupervised learning. I also developed a target likelihood estimation method for collaborative sensing.
I have extensive research experience on ITS applications including the development of vehicle detection and tracking algorithms and vision-based lane and obstacle detection algorithms for a collision warning system. One of the vehicle detection and tracking algorithms was adopted by the Next Generation Simulation program (NGSIM) of the Federal Highway Administration to generate a widely used database of high quality vehicle trajectories.
Geographic information systems (GIS) is an important emerging research area. Aerial imageanalysis is a key technology of GIS that requires significant automation. Through my Ph.D. thesis work, I have increased the level of complexity of the buildings that can be automatically detected and described.
I have worked on various other areas in computer vision and its related topics including: camera motion analysis, video sequence analysis, edge detection, optical flow estimation, and non-photorealistic rendering. I have also been a teaching assistant for Artificial Intelligence and for Computer Graphics and Virtual Reality.
