Local features for RGBD image matching under viewpoint changes 主讲人：法国国家科研中心 Frederic Dufaux教授 时 间：2016年11月8日（周二）14：30地 点：电子科技大学清水河校区品学楼B106主持人：电子科技大学电子工程学院 朱策教授主办单位：电子科技大学人力资源部教师发展中心承办单位： 电子科技大学电子工程学院、机器人研究中心
内容简介： In the last five-to-ten years, 3D acquisition has emerged in many practical areas thanks to new technologies that enable a massive generation of texture+depth (RGBD) visual content, including infrared sensors Microsoft Kinect, Asus Xtion, Intel RealSense, Google Tango, laser 3D scanners (LIDARs).
The increasing availability of this enriched visual modality, combining both photometric and geometric information about the observed scene, opens up new horizons for different classic problems in vision, robotics and multimedia. In this thesis, we address the task of establishing local visual correspondences in images, which is a basic task that numerous higher-level problems are settled with.
The local correspondences are commonly found through local visual features. While these have been exhaustively studied for traditional images, little work has been done so far for the case of RGBD content.
In this talk, we contribute with several new approaches of keypoint detection and descriptor extraction, that preserve the conventional degree of keypoint covariance and descriptor invariance to in-plane visual deformations, but aim at improved stability to out-of-plane (3D) transformations in comparison to existing texture-only and texture+depth local features.
In order to assess the performance of the proposed approaches, we revisit a classic feature repeatability and discriminability evaluation procedure, taking into account the extended modality of the input. Along with this, we conduct experiments using application-level scenarios on RGBD datasets acquired with Kinect sensors. The results show the advantages of the new proposed RGBD local features in terms of stability under viewpoint changes. 主讲人简介： Dr. Frederic Dufaux is a CNRS Research Director at Telecom ParisTech.

Being There: Augmented Reality for Remote Collaboration 主讲人 University of California, Santa Barbara Matthew Turk IEEE/IAPR Fellow时 间 2016年11月6日（周日） 9:00-10:00地 点电子科技大学清水河校区图书馆求实厅（600人报告厅）主持人 电子科技大学自动化工程学院/机器人研究中心 程洪 教授内容简介 Collaborating remotely on tasks that require engagement with the physical environment is difficult with existing videoconferencing technologies, since they do not adequately support a shared 3D space or ways to effectively communicate spatial information.
We propose a framework for unobtrusive mobile telecollaboration that integrates the physical environment, supporting rich interaction by using computer vision-based tracking and mapping, along with augmented reality techniques to communicate spatial information about a novel scene.
This allows for a decoupling of the participants’ views of the environment based on a real-time tracking and mapping technique that supports general camera motion (both rotation-only and translational movement) in the 3D environment.
The approach effectively integrates panorama mapping and tracking with a keyframe-based SLAM system, behaving like one or the other depending on the camera movement, with no prior information about the environment. We describe the framework and prototype system, user studies to evaluate the benefits of the interface, and promising applications of the technology. 主讲人简介 Matthew Turk is a professor of Computer Science and former chair of the Media Arts and Technology program at the University of California, Santa Barbara, where he co-directs the UCSB Four Eyes Lab, focused on the “four I’s” of Imaging, Interaction, and Innovative Interfaces.
He received a B.S. from Virginia Tech, an M.S. from Carnegie Mellon University, and a Ph.D. from the Massachusetts Institute of Technology. Before joining UCSB in 2000, he worked at Microsoft Research, where he was a founding member of the Vision Technology Group in 1994.
He is on the editorial board of the ACM Transactions on Intelligent Interactive Systems and the Journal of Image and Vision Computing, and he serves on advisory boards for multiple conferences. Prof. Turk has received several paper awards and has been general or program chair for several major conferences, including CVPR 2014 and WACV 2017.

LIMIT CYCLES IN DISCONTINUOUS PIECEWISE LINEAR DIFFERENTIAL SYSTEMS WITH TWO PIECES SEPARATED BY A STRAIGHT LINE 时间：2016年11月7日15：00-17：00地点：西南石油大学思学楼C304主讲人：Prof. Dr. Jaume Llibre报告内容：
First we shall present what it is known about the limit cycles of the discontinuous piecewise linear differential systems with two pieces separated by a straight line. Second we shall describe briefly four different techniques for computing analytically the limit cycles of the mentioned discontinuous piecewise linear differential systems, based on the averaging theory or Melnikov integral, the first integrals, the Poincar´e map, and the Poincar´e map plus the Newton-Kantorovich Theorem. 报告人简介：Prof. Dr.Jaume Llibre，Universitat Aut`onoma de Barcelona Academician，世界著名数学家、西班牙皇家科学院院士，巴塞罗那自治大学Jaume Llibre教授来我校访问。Jaume Llibre于1979年在西班牙巴塞罗那自治大学（Universitat Aut`onoma de Barcelona）获得博士学位，2002年评选为西班牙皇家科学院院士。
