In this talk, we look into the problem of segmenting, tracking, and  extracting 3D time varying shape and camera poses for non-rigid objects in monocular videos.  Our method segments and tracks objects and their parts using past segmentation and tracking experience from a training set, and uses the segmented point trajectories of each object to extract 3D shape assuming a low-rank shape prior.  We segment using motion boundaries and learnt saliency detection, and outperform by a margin the previous state-of-the-art in challenging video scenes.  We ``learn to track’’ usin

Presenter's Biography:

Katerina Fragkiadaki is a post doctoral researcher at the Computer Vision laboratory at UC Berkeley, working with Prof. Jitendra Malik. Before that, she completed her Ph.D. in the GRASP Laboratory, at University of Pennsylvania, where she was advised by Prof. Jianbo Shi. Katerina is interested in all aspects of video understanding. In particular, she has been working on estimating human motion and body pose in videos as a means towards inferring what people are doing or want to do next.

In this talk, I will present a number of methods for increasing the versatility of mobile manipulators, from novel hand designs and grasp planning algorithms to Human-in-the-Loop manipulation and its applications in assistive robotics. I will introduce the concept of eigengrasps as the bases of a linear hand posture subspace, and use it to show that, from a grasp planning perspective, a hand does not have to be complex in order to be versatile.

Presenter's Biography:

Matei Ciocarlie is an assistant professor of Mechanical Engineering at Columbia University. His main interest is in reliable robotic performance in unstructured, human environments, focusing on areas such as novel robotic hand designs and control, autonomous and Human-in-the-Loop mobile manipulation, shared autonomy, teleoperation, and assistive robotics. Matei completed his Ph.D. at Columbia University; his doctoral dissertation, focused on reducing the computational complexity associated with dexterous robotic grasping, was the winner of the 2010 Robotdalen Scientific Award. Before joining the Mechanical Engineering faculty at Columbia, Matei was a Research Scientist and then Group Manager at Willow Garage, Inc., a privately funded Silicon Valley robotics research lab, and then a Senior Research Scientist at Google, Inc. In these positions, Matei contributed to the development of the open-source Robot Operating System (ROS), and led research projects in areas such as hand design, manipulation under uncertainty, and assistive robotics. In recognition of his work, Matei was awarded the 2013 IEEE Robotics and Automation Society Early Career Award.

Bipedal Walking is a balance critical full body motion that demands fast controller response in order to maintain stability with the right steps at the right time. Aside from the complexity of the walking motion itself, sensor and actuation noise on real hardware combined with latency in the sensomotoric feedback loop make the computation of well placed footsteps a particularly challenging task. In this presentation, an inverted pendulum based method will be introduced that produces an omnidirectional walk with a good amount of stability for various disturbances.

Presenter's Biography:

Marcell Missura is a PhD student at the University of Bonn in Germany. His focus is the research of bipedal walking. Marcell is also the team leader of the robot soccer team NimbRo that earned the world champion title in the TeenSize class of the RoboCup Humanoid League several years in a row.
