"Reconstructing Reality: From Physical World to Virtual Environments"
April 7, 2017, 11:30am-12:30pm
With increasing availability of data in various forms from images, audio, video, 3D models, motion capture, simulation results, to satellite imagery, representative samples of the various phenomena constituting the world around us bring new opportunities and research challenges. Such availability of data has led to recent advances in data-driven modeling. However, most of the existing example-based synthesis methods offer empirical models and data reconstruction that may not provide an insightful understanding of the underlying process or may be limited to a subset of observations.
In this talk, I present recent advances that integrate classical model-based methods and statistical learning techniques to tackle challenging problems that have not been previously addressed. These include flow reconstruction for traffic visualization, learning heterogeneous crowd behaviors from video, simultaneous estimation of deformation and elasticity parameters from images and video, and example-based multimodal display for VR systems. These approaches offer new insights for understanding complex collective behaviors, developing better models for complex dynamical systems from captured data, delivering more effective medical diagnosis and treatment, as well as cyber-manufacturing of customized apparel. I conclude by discussing some possible future directions and challenges.

CECS Research Seminar Series: Dr. Rajesh Rajamani
"Novel Sensors, New Estimation Algorithms and Active Controls: Technologies for Improving Highway Vehicle Safety and Mobility"
April 14, 2017, 11:30am-12:30pm
A number of exciting vehicle automation and active safety systems are being developed by research groups around the world. This talk focuses on novel sensors, estimation algorithms and control systems that can fill critical gaps in the automation technologies under development. The first part of this seminar describes interesting sensing and estimation solutions that can significantly improve the effectiveness of active safety systems. The solutions discussed here include piezoelectric tire deformation sensors, observers for parameter varying nonlinear systems, unknown disturbance observers for predicting and preventing tripped rollovers, and magnetic sensors for detection of imminent unavoidable crashes. The second part of the seminar describes the development of a new class of narrow commuter vehicles designed to address traffic congestion, improve highway mobility and provide very high fuel economy. Results from a prototype narrow vehicle with stability-enhancing automatic tilt control developed at the University of Minnesota are presented. The final part of the seminar describes the development of a smart bicycle with instrumentation that can track trajectories of nearby vehicles on the road and provide warnings to the motorist, if a potential car-bicycle collision is detected. Significant challenges from sensor cost and size constraints for a bicycle, and from the need to track highly complex collision scenarios are discussed. Experimental results and videos of the smart bicycle system’s performance are presented.
