Robotics and Cyber-Physical Systems are ushering in a new age of engineering design with new techniques and new materials. The old way of design in which we assume decoupled, low-order, block-diagonal models is breaking down at all levels and all scales. This presents numerous problems as our ad hoc design methods are not able to properly account for, test and validate systems of greatly increasing complexity.

Object detection is one of the fundamental challenges in computer vision.  In this talk I will consider the problem of detecting objects from a generic category, such as people or cars, in static images. This is a difficult problem because objects in such categories can vary greatly in appearance. For example, people wear different clothes and take a variety of poses while cars come in various shapes and colors. We have built an object detection system that addresses this challenge using mixtures of deformable part models.

Motivated by problems in structural biology, specifically cryo-electron microscopy, we introduce vector diffusion maps (VDM), a new mathematical framework for organizing and analyzing high dimensional data sets, images and shapes. VDM is a mathematical and algorithmic generalization of diffusion maps and other non-linear dimensionality reduction methods, such as LLE, ISOMAP and Laplacian eigenmaps. While existing methods are either directly or indirectly related to the heat kernel for functions over the data, VDM is based on the heat kernel for vector fields.

In this talk, we will present shape registration algorithms based on the implicit distance function representation. In its implicit representation, a shape is embedded in a higher-dimensional space as the zero level set of a distance function. In certain applications like shape registration, the implicit representation has advantages because it provides additional support to the registration process and requires matching of not only the shapes but also their clones that are positioned coherently in the embedding space.

From the very beginning of robotics and telerobotics, we have envisioned using a robot to be our presence at a second location. This includes seeing what the robot sees, feeling what the robot feels. And it is still true today - operators sooner or later want to feel the remote world. Traditional wisdom suggests feeding back sensor information to the user as directly as possible, making the system as transparent as possible. Yet this has always left us in a tight bind between performance and stability.

Presenter's Biography:

Dr. Günter Niemeyer is a senior research scientist at Willow Garage Inc. and a consulting professor of Mechanical Engineering at Stanford University. His research examines physical human-robotic interactions and interaction dynamics, force sensitivity and feedback, teleoperation with and without communication delays, and haptic interfaces. This involves efforts ranging from realtime motor and robot control to user interface design. Dr. Niemeyer received his M.S. and Ph.D. from MIT in the areas of adaptive robot control and bilateral teleoperation, introducing the concept of wave variables. He also held a postdoctoral research position at MIT developing surgical robotics. In 1997 he joined Intuitive Surgical Inc., where he helped create the daVinci Minimally Invasive Surgical System. This telerobotic system enables surgeons to perform complex procedures through small (5 to 10mm) incisions using an immersive interface and is in use at hundreds of hospitals worldwide. He joined the Stanford faculty in the Fall of 2001, directing the Telerobotics Lab and teaching dynamics, controls, and telerobotics. He has been a member of the Willow Garage research group since 2009.
