PhD student Seoing Il Lee (advisor : Yong Man Ro) received Outstanding Paper Award from 2013 Global 3D Tech Forum on October 10~11 2013 with a paper titled “Investigating the effect of combined convergence and focal length adjustment on visual comfort in stereoscopic camera applications”

 

 

 

Abstract

This paper investigated the effect of combined convergence and focal length adjustment on visual comfort in stereoscopic camera applications. To this purpose, subjective assessments were conducted. Experimental results show that the combined adjustment can provide significant improvement of visual comfort and overall viewing quality.

 

PhD student Semin Kim (advisor : Yong Man Ro) received Outstanding Paper Award from 2013 Korea Multimedia Society Spring Conference with paper titled “Analysis of the Robustness and Discrimination for Video Fingerprints in Video Copy Detection”

Abstract

In order to prevent illegal video copies, many video fingerprints have been developed. Video fingerprints should be robust from various video transformations and have high discriminative powers. In general, video fingerprints are generated from three feature spaces such as luminance, gradient, and DCT coefficients. However, there is a few study for the robustness and discrimination according to feature spaces. Thus, we analyzed the property of each feature space by video copy detion task with the robustness and the discrimination of video fingerprints. We generated three video fingerprints from these feature spaces using a same algorithm. In our test, a video fingerprint. based on DCT coefficient outperformed others because the discrimination of it was higher.

PhD students Younghwan Go, Shinae Woo (advisor : KyoungSoo Park), Prof. KyoungSoo Park and Yongdae Kim received BEST PAPER AWARD from The 5th Annual Wireless of the Students, by the Students, for the Students Workshop (ACM S3 2013) on Septermber 30 2013 with paper titled “Impact of Malicious TCP Retransmission on Cellular Traffic Accounting”

ABSTRACT
Current cellular network architecture charges users based on the consumed IP traffic in byte-level. While the users receive payload at the application layer, there exists a transport layer (TCP) that can cause additional data consumption due to the retransmission that guarantees a reliable delivery. In this paper, we examine the accounting policies regarding the TCP’s retransmission in five major cellular ISPs in the U.S. and South Korea and show that the current implementation is either vulnerable to billing inflation or allows the subscribers to bypass the charging. Two ISPs account for all retransmission packets, allowing attackers to inflate a victim’s bill by intentionally retransmitting packets. Three ISPs exclude the retransmission packets from the user’s bill thus allowing tunneling through TCP retransmissions. We present real-world attack scenarios where “usage-inflation” and “free-riding” attacks are plausible.

PhD student Jee-Hoon Lee (advisor : Seong-Ook Park) received BEST STUDENT PAPER AWARD from 2013 international symposium on antennas and propagation (isap 2013) on October 23 ~ 25 2013 with paper titled “A 14 ghz non-contact radar system for long range heart rate detection”

 

 

Abstract

This research presents a 14 GHz CW Doppler radar to measure respiration and heart rate. A leakage cancellation technique is used to detect heart rate of human for long range detection. Arctangent demodulation without the dc offset compensation can be applied because of the heterodyne receiver structure and the leakage cancellation technique. HRV analysis of the radar system and the ECG signal which is measured directly are compared. Based on the measurement results, the radar can detect the respiration and heart rate with a small error rate.

PhD student Changbeom choi (advisor : Tak Gon Kim) received BEST PAPER AWARD from The 10th International Multidisciplinary Modeling & Simulation Multiconference 2013 on September 26 2013 with the paper titled 『Serious game development methodology by via interoperation between a constructive simulator and a game application using HLA/RTI』

 

 

ABSTRACT
This paper proposes a serious game development methodology that utilizes interoperation between an existing virtual world application and constructive simulators. For time synchronization and data conversion between them, the proposed methodology is comprised of three specified processes: game loop analysis, game agent design and development, and parameter tuning. We use a High-Level Architecture (HLA) to ensure interoperation. By interoperating a constructive simulator with an existing virtual world application, a serious game developer can save effort by extending a serious game application, rather than building a serious game from scratch. In addition, trainees can obtain more realistic experiences.
