I continue to work at Brown 20% of my time but a I am not accepting new students at Brown.
Vision, graphics, and Kinect programmers wanted in my group at Max Planck.
For post doctoral positions in my department at Max Planck see this job announcement.
If you are a PhD student interested in working with me at Max Planck please contact my assistant, Melanie Feldhofer.
New BMI visualizer on-line. Visulize your BMI and learn how BMI relates to body shape using our 3D body visualization tool.
Research Interests
My Computer Vision Research focuses on estimating optical flow from sequences
of images. In particular I study
 the
statistics of natural images and image motion;
articulated
human motion estimation and tracking;
the estimation of human body shape from images and video;
the representation and
detection of motion discontinuities;
the
estimation of optical flow.
I also do research on neural engineering for brain-machine interfaces and neural prostheses.
