CVL Seminar: Namrata Vaswani, Recursive Sparse Recovery and Applications in Dynamic Imaging". Date: March 30, 2011 Time: 11:00 am Location: AV Williams 1146 In this talk, I will discuss our recent work on Recursive Sparse Recovery (RecSparsRec) and show how it provides novel solutions to two very different problems in dynamic imaging. RecSparsRec refers to recursive approaches to causally recover a time sequence of signals/images from a greatly reduced number of measurements (compared to existing approaches), by utilizing their sparsity. I will also briefly talk about our ongoing work on the...  read more
CVL Seminar: Daniel Glasner, Contour Based Joint Clustering of Multiple Segmentations". Date: March 29, 2011 Time: 11:00 am Location: AV Williams 3258 We present an unsupervised shape based method for joint clustering of multiple image segmentations. Given two or more tightly related images, such as close frames in a video sequence, or images of the same scene taken under different lighting conditions, our method generates a joint segmentation of the images. We introduce a novel contour based representation that allows us to cast the shape-based joint clustering problem as a quadratic semi-...  read more
During the past few months, twelve students have been researching and preparing for the Collegiate Cyber Defense Competition. After winning a qualifying round against the defending champions and gaining a place in the regional finals, the team sent eight of their most qualified members to compete in the Mid-Atlantic regional CCDC. The team was put to the test at the competition as a thirty member red team sent attacks ranging from back doors and scripts to a late night hardware attack and Nerf gun firing squad. After two days of defending their boxes against the relentless red team attacks...  read more
Distinguished Seminar Series on Vision in honor of Prof. Azriel Rosenfeld presents Bill Freeman, MIT, Removing blur due to camera shake from images". Date: March 11, 2011 Time: 11:00 am Location: CSIC Building, Room 1115 "Blind deconvolution" is a beautiful, ill-posed problem: given an image that has been blurred by some unknown convolution kernel, estimate the image before it was blurred. Lurking within this problem are nice, deep questions: What is an image, and how can you tell when one has been blurred? How should we solve very underdetermined inference problems?  read more
Ravi Ramamoorthi, University of California, Berkeley talks about Sampling and Reconstruction of High-Dimensional Visual Appearance". Date: March 9, 2011 Time: 11:00 am Location: A.V. Williams Building, Room 2120 Producing realistic images in computer graphics, or acquiring the visual properties of realistic scenes in computer vision, often involves sampling high-dimensional datasets. One example comes from real-time rendering techniques, that often use a precomputed light transport matrix that can range from 4D - 6D, measuring variation across the image, as well as the space of lighting and...  read more
CVL Seminar: Shawn D. Newsam, University of California, Merced talks about Proximate Sensing: Inferring What-Is-Where From Georeferenced Photo Collections". Date: March 9, 2011 Time: 3:00 pm Location: A.V. Williams Building, Room 2120 In this talk, I will describe an interesting new research direction which I term Proximate Sensing that leverages ground-level georeferenced images to map what-is-where on the surface of the Earth much like the field of Remote Sensing has done for decades using overhead imagery. Enabled by the growing collections of community contributed photo collections,...  read more
March 4, 2011 NPR, Undergraduates Ederlyn Lacson and Ray Douglas were interviewed by NPR about the strong job market for CS students. "Want A Job? You Ought To Be A Tech Geek".  read more
Prof. Ben Shneiderman will be presented with the prestigious Miles Conrad Award on February 28, 2011 at the National Federation of Advanced Information Services ( NFAIS ) 53rd Annual Conference in Philadelphia, PA. The purpose of the award is to recognize and honor those members of the Information Community who have made significant contributions to the field of information science and to the NFAIS itself.  read more
Spring Colloquium presents Jandelyn Plane, Senior Lecturer. Title: Exploring Computer Science Gender Parity through Research in Afghanistan Date: February 7, 2011 Time: 4:00 pm Location: ECE Conference Room. AVW 2460 Through USAID, Jan Plane has been working with Computer Science Departments in underdeveloped countries of Africa and Asia for the pastdecade assisting them in curriculum development and capacity building.While visiting Afghanistan to work with their professors, she noticedan unusually high percentage of women in their computer scienceclasses. This talk will present lessons...  read more
Russell H. Taylor, Johns Hopkins University, talks about "Medical Robotics and Computer-Integrated Interventional Medicine". Date: January 31, 2011 Time: 11:00 am Location: A.V. Williams Building, Room 2460 This talk will discuss ongoing research at the NSF Engineering Research Center for Computer-Integrated Surgical Systems and Technology (CISST ERC) to develop systems that combine innovative algorithms, robotic devices, imaging systems, sensors, and human-machine interfaces to work cooperatively with surgeons in the planning and execution of surgery and other interventional procedures. This...  read more
