Manmohan ChandrakerI lead the Media Analytics group at NEC Labs America. We work on computer vision, in particular large-scale image recognition and 3D scene understanding. My personal research interests are 3D reconstruction and graphics-based vision, with applications in autonomous driving, robotics and HCI. My PhD was from UC San Diego with Prof. David Kriegman, before a postdoc at UC Berkeley with Prof. Ravi Ramamoorthi.E-mail: manu [AT] nec - labs . com |
3D Visual Sensing for Automated Driver Assistance: Our team is developing a real-time traffic scene understanding system that uses a single camera to localize traffic participants in 3D, for applications like collision avoidance and dangerous event prediction.

Global Light Transport: I have developed theory and algorithms for photometric 3D reconstruction that can handle global light transport effects, such as inter-reflections and shadows. I have also worked on methods to invert such global effects in projector-camera systems.
