Student News

Alyse Stone (MAE, senior) and her teammates, GW students Henry Palancar and Rhiannon Scanlon, formed the student start-up Koti, and won Honorable Mention and $2,500 at the Texas Christian University Values and Ventures Competition, held April 11-12 at the university.  The competition is an annual event for undergraduate students around the world to pitch plans for for-profit enterprises that impact society in meaningful ways.  Koti aims to revolutionize the way international NGOs, relief organizations, and governments aid individuals impacted by natural disasters. The team has developed a product that provides families temporary homes in the form of a compact cube that is affordable, lightweight, and easy to use.  It uses green technology and sustainable materials, and it includes a bed, a renewable light source, and clean water.

Qi Wang (CS, doctoral student), along with Prof. Gabriel Parmer (CS), received the Best Student Paper Award at the IEEE Real-Time and Embedded Technology and Applications Symposium for their paper “FJOS: Practical, Predictable, and Efficient System Support for Fork/Join Parallelism.”  The symposium was held April 15-17, in Berlin, Germany.

Statistical Modeling Approaches in Image Understanding

A picture is worth a thousand words, and understanding a picture by a computer is an important and difficult problem, since it carries large amount of information.  As sensor and computer technologies improve at a dramatic pace, the amount and types of image data also increase faster than they can be processed manually.  There are image sensors in space, in the air, and on the ground, and some are used for biomedical applications.  Image sensors cover spectral ranges from the microwave (synthetic aperture radar), infrared (IR), and visual spectra.

Professor Eom’s research develops algorithms by modeling images using statistical methods.  To apply statistical modeling approaches, images are assumed to have certain properties.  For example, an image is assumed to be complex enough to be viewed as a random field.  Then a model is developed and an image is characterized by estimating the parameters of the model.  Professor Eom is working on applications of this approach in collaboration with his former visiting scholars, Professor Jongho Kim and Dr. Peng Liu, as well as with graduate students.  Examples include the reduction of speckle in synthetic aperture radar (SAR) and ultrasound images, reduction of the blocking effect in image compression algorithms, the restoration of images by total variation, and compressed sensing of multispectral images.  (Provided courtesy of Professor Kie- Bum Eom of the Department of Electrical and Computer Engineering)
