Friday March 4, 2011 from 11:00am to 12:00pm
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.

Friday February 18, 2011 from 11:00am to 12:00pm
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.

This talk reports a brief overview of
the Nereus vehicle design, and
reviews the initial results of the dives conducted on these expeditions,
including two dives to more than 10,900 m depth. In May/June 2009 Nereus successfully performed scientific observation and sampling
operations at hadal depths of 10,903 m on a NSF sponsored expedition to the Challenger Deep
of the Mariana Trench – the deepest place on Earth. In October 2009 the vehicle successfully
performed autonomous survey and tel
Louis L. Whitcomb completed his Ph.D. degree at Yale University in 1992. His research focuses on the dynamics and control of robot systems – including industrial, medical, and underwater robots. Whitcomb is a principal investigator of the Nereus Project. He is founding Director of the JHU Laboratory for Computational Sensing and Robotics. Whitcomb is a Professor in the Department of Mechanical Engineering, with secondary appointment in the Department of Computer Science, at the Johns Hopkins University’s Whiting School of Engineering, and Adjunct Scientist, Department of Applied Ocean Physics and Engineering, Woods Hole Oceanographic Institution.

* Alternate Location: Levine 307 (3330 Walnut Street)*
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.
Amit Singer is an Associate Professor of Mathematics and a member of the Executive Committee of the Program in Applied and Computational Mathematics (PACM) at Princeton University. He joint Princeton as an Assistant Professor in 2008. From 2005 to 2008 he was a Gibbs Assistant Professor in Applied Mathematics at the Department of Mathematics, Yale University. Singer received the BSc degree in Physics and Mathematics and the PhD degree in Applied Mathematics from Tel Aviv University (Israel), in 1997 and 2005, respectively. He served in the Israeli Defense Forces during 1997-2003. He was awarded the Alfred P. Sloan Research Fellowship (2010) and the Haim Nessyahu Prize for Best PhD in Mathematics in Israel (2007). His current research in applied mathematics focuses on problems of massive data analysis and structural biology.
Presenter: Xiaolei Huang (Homepage)
Monday December 20, 2010 from 1:00pm to 2:00pm
* Alternate Location: Levine 512 (3330 Walnut Street)*
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.
Xiaolei Huang received her B.E. degree in Computer Science from Tsinghua University, China in 1999, and her M.S. and Ph.D. degrees in Computer Science from Rutgers University in 2001 and 2006, respectively. She is currently an Assistant Professor in the Computer Science and Engineering department at Lehigh University, Bethlehem, PA. Her research interests are in the areas of computer vision, biomedical image analysis, and computer graphics, focusing on registration, segmentation, and deformable model based methods.

Presenter: Gunter Niemeyer (Homepage)
Friday December 10, 2010 from 11:00am to 12:00pm
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.
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.
