  •  TALK   Visual 3D/4D modeling of urban places and events
    Date & Time: Friday, June 29, 2012; 2:30 PM
    Speaker: Prof. Marc Pollefeys, ETH Zurich and UNC Chapel Hill
    Research Area: Computer Vision
    Brief
    • One of the fundamental problems of computer vision is to extract 3D shape and motion from images. This can be achieved when a scene or object is observed from different viewpoints or over a period of time. First, we will discuss image-based 3D modeling and localization in large environments, e.g. urban 3D reconstruction from vehicle-borne cameras and (geo)localization from mobile-phone images. In this context, we will discuss some of the challenges an opportunities offered by symmetries of architectural structures. We will also discuss how changes in an urban environment can be detected from images, leading to the possibility to efficiently acquire 4D models. In addition to explicit 4D modeling of an event, we'll consider the possibility to perform interactive video-based rendering from casually captured videos.

  •  EVENT   ACC 2012 - Sponsored Session: Oppportunities at Mitsubishi Electric Research
    Date & Time: Wednesday, June 27, 2012; 12:00 PM - 1:30 PM
    MERL Contact: Scott Bortoff
    Location: Montreal, Canada
    Brief
    • In this session, MERL researcher Scott Bortoff will describe Mitsubishi Electric Corporation (MELCO)'s businesses, discuss mechatronics and controls research at MERL and describe opportunities for collaboration and employment. Areas of current research interest include optimal control especially of nonlinear and hybrid systems, model predictive control, nonlinear dynamical systems, and modeling and control of multi-physical heterogeneous systems. Research projects at MERL typically address fundamental problems that are industrially-motivated, and involve application of advanced control theory or dynamical systems theory to MELCO products resulting in new technology that is transferred into the corporate R&D laboratories for subsequent product development. Areas of current application include elevators, HVAC, power generation and distribution, satellites, robot manipulation, servo systems and laser processing systems. MERL has a tradition of open collaboration and hosts visitors and interns especially during the summer months when our population increases by 50%. Researchers and students who have an interest in collaboration, visits, sabbatical leaves or permanent employment are invited.

  •  TALK   Toward Efficient and Robust Human Pose Estimation
    Date & Time: Tuesday, June 26, 2012; 12:00 PM
    Speaker: Min Sun, University of Michigan
    Research Area: Computer Vision
    Brief
    • Robust human pose estimation is a challenging problem in computer vision in that body part configurations are often subject to severe deformations and occlusions. Moreover, efficient pose estimation is often a desirable requirement in many applications. The trade-off between accuracy and efficiency has been explored in a large number of approaches. On the one hand, models with simple representations (like tree or star models) can be efficiently applied in pose estimation problems. However, these models are often prone to body part misclassification errors. On the other hand, models with rich representations (i.e., loopy graphical models) are theoretically more robust, but their inference complexity may increase dramatically. In this talk, we present an efficient and exact inference algorithm based on branch-and-bound to solve the human pose estimation problem on loopy graphical models. We show that our method is empirically much faster (about 74 times) than the state-of-the-art exact inference algorithm [Sontag et al. UAI'08]. By extending a state-of-the-art tree model [Sapp et al. ECCV'10] to a loopy graphical model, we show that the estimation accuracy improves for most of the body parts (especially lower arms) on popular datasets such as Buffy [Ferrari et al. CVPR'08] and Stickmen [Eichner and Ferrari BMVC'09] datasets. Our method can also be used to exactly solve most of the inference problems of Stretchable Models [Sapp et al. CVPR'11] on video sequences (which contains a few hundreds of variables) in just a few minutes. Finally, we show that the novel inference algorithm can potentially be used to solve human behavior understanding and biological computation problems.

  •  TALK   A Real-Time Algorithm for Nonlinear Model Predictive Control and Its Applications
    Date & Time: Monday, June 25, 2012; 10:30 AM
    Speaker: Prof. Toshiyuki Ohtsuka, Osaka University
    MERL Host: Stefano Di Cairano
    Brief
    • In this talk, a real-time algorithm for nonlinear model predictive control and its applications will be introduced. The continuation method is combined with an efficient linear solver GMRES to trace the time-dependent optimal solution without iterative searches. Applications of the algorithm include position control of an underactuated hovercraft, route tracking of a ship with redundant actuators, and path generation for an automobile. Automatic code generation by symbolic computation and other related topics will also be introduced.
