Research Papers Win Awards at Prestigious Conferences

Two CSE research teams have recently been recognized with Best Paper Award and Best Student Poster Award respectively at World's Prestigious Conferences on Computer Science.

The paper "Opportunity-based Topology Control in Wireless Sensor Networks" co-authored by Yunhuai LIU, Dr. Qian ZHANG and Prof. Lionel M. NI beat over 600 other papers to win the Best Paper Award at the IEEE International Conference on Distributed Computing Systems 2008 in Beijing.

This Opportunity-based Topology Control system effectively improves the energy efficiency of wireless sensor networks (WSNs). "Traditional approaches are based on the deterministic network model that assumes wireless links are either connected or disconnected. As a result, the network behavior results based on this deterministic network model cannot reflect the performances realistically." In order to solve the problem, they proposed a new probabilistic network model using several heuristic algorithms which show promising results.

ICDCS is an IEEE Computer Society sponsored premier conference with a wide coverage of topics in Distributed Computing. It has a long history of significant achievements and worldwide visibility. The conference provides a forum for engineers and scientists in academia, industry and government to present their latest research findings in any aspects of distributed and parallel computing.

Another award-winning team involves Jia CHEN, Lu YUAN and Dr. Chi-Keung TANG and Prof. Long QUAN from the Visgraph research group. Their research paper "Robust Dual Motion Deblurring" received the Best Student Poster Award at the IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR) held in Alaska.

This paper targets at motion deblurring problem for digital photograph - removing photo blur caused by camera shake. It doesn't require professional DSLR functions or any other special hardware, thus providing great convenience for consumer level photography. The algorithm of this paper is based on solid analysis of the state-of-the-art approaches and novel use of robust techniques to make big improvements.

The IEEE CVPR conference is one of the best three vision conferences all over the world (the other two are ICCV and ECCV). Our lab has consistent publications on this conference every year. This award is the first award we've got from CVPR but not the last.
