Moving from HD to Ultra HD (UHD) has become a trend in the display industry as UHDTV systems can provide better user experience such as stronger sensations of reality and superior picture quality. In SMPTE 2013 symposium, it is forecasted that the shipments of UHDTV sets are expected to reach four million units by 2017.

Act as one of the leading groups in video processing research, MCL lab is currently one of the pioneers in exploring UHD video processing technology. The lab has setup a UHD display with high performance playback system. The purpose of the system is to provide the playback of 4K UHD (i.e., 3840×2160 resolution) raw video data in real-time: 60 frame/sec at minimum and up to 120 frames/sec. Besides, to address the concern that a lack of native UHD contents will limit the research, a professional UHD acquisition system will also be available in the lab soon. We expect that this UHD system can help us create more research topics and produce more UHD contents for the researchers who are interested in the technology of video processing.

The UHD system in MCL lab:

Acquisition: Sony 4K professional handheld camcorder
Display: 65” Samsung 4K Ultra HD Smart TV
Playback: High performance Dell Precision workstation supporting 4K raw video playback up to 120 FPS

The Google LA PhD Summit 2014 was held on February 14th at Google LA site. Jian Li, Hao Xu, Jia He and Xin Zhang from MCL attended the event. They were invited to several events from Google including a keynote talk “Music Understanding”, presentations about “Large-Scale Machine Learning”, “Language Understanding”, “Chrome Security” and “Vision + Quantum”. Besides, they had a good chance to talk with leading Google PhDs, and got the opportunities to meet with Google engineers and project managers.

During the information session, engineers from Google mainly introduced researching differences between academia and Google. Two key differences are about available resources and the motivation of the research. Firstly, Google has the most powerful computer center, which offers almost infinite computation resources. They can train very complicated models, adopt more training samples, and obtain results almost instantly with the help from Google. This is crucial for current computer vision research. Secondly, as of motivation, researchers have no pressure on the quantity of publication. Instead, the quality of the publication plays more important role when they publish papers. Additionally, Google has no limit on sharing the work to research community, but they prefer to share the practical work instead of theories only. Several research scientists pointed out that they fundamentally traded the community work to coding when they move from academia to Google.

Besides, they have learned more about the ongoing research work in Google. Hartwig Adam, who is the technical lead manager of the Visual Search team in LA office, shared his work there. His team is focusing on developing computer vision algorithms and a scalable computer vision application such as image and video searching, data mining. He also works for Google Goggles and Glass. They [...]

Dr. Hui Yong Kim, a senior researcher of Broadcasting and Telecommunications Media Research Laboratory of Electronics and Telecommunications Research Institute (ETRI) and also a former adjunct professor at University of Science and Technology (UST) in Korea, visited Media Communication Lab since September 2013. He generously spent some of his short time with us to share his research.

Could you give us a brief introduction about your research experience?

I would like to start from my PhD research experience. I worked on visual surveillance project during my PhD years, and the project required object detection and segmentation from videos. By separating background and foreground, I compressed detected objects and background differently to increase quality of objects area. After graduation, I joined a start-up company because I wanted to get a whole picture of how the real devices are developed. There, I mainly developed H.264 real-time codec software for several video communication systems, such as IP video phone and other consumer products. Because I was a manager in multimedia team, I also needed to care other issues like middle-wares, communication protocols, audio codecs, graphical user interfaces, and even mechanical designs. After few years, I decided to move to ETRI to continue my research path. In ETRI, I participated and contributed to developments of several international standards, including MPEG Multimedia Application Formats and High Efficiency Video Coding (HEVC). During the process, I developed more than 70 patent algorithms.

Could you also talk about your research interest?

My research interests include video/image signal processing and compression for realistic video services, such as UHDTV and 3DTV. They are called as “realistic media”, which implies making things real to human. My research goal is how to maximize visual reality to the user efficiently under [...]

The Asia-Pacific Signal and Information Processing Association (APSIPA) is a non-profit organization with the following objectives as its mission:
1) Providing education, research and development exchange platforms for both academia and industry
2) Organizing common-interest activities for researchers and practitioners
3) Facilitating collaboration with region-specific focuses and promoting leadership for worldwide events
4) Disseminating research results and educational material via publications, presentations, and electronic media
5) Offering personal and professional career opportunities with development information and networking
The idea of APSIPA was born in Hawaii in 2007. It was formally incorporated as “Asia Pacific Signal and Information Processing Association Limited” in Hong Kong on July 23, 2009. Dr. Sadaoki Furui was elected as the first President and all other BoG members were elected at the BoG meeting held on the first day of APSIPA ASC 2009, October 4, 2009. Professor C.-C. Jay Kuo succeeded Dr. Furui to become the 2nd President of APSIPA in 2013 December.
The APSIPA Board of Governs (BoG) has set up a goal to reach 400 APSIPA Friend Labs and 5000 e-membership before the end of 2014. The membership drive consists 4 phases with 3 months per phase. By the end of Phase I (1/31/2014), APSIPA had 112 Friend Labs and 2002 e-members. The target goal (100 Friend Labs and 2000 e-members) was reached. This success was attributed to the joint and tireless of APSIPA leaders. All MCL members have worked together to promote APSIPA and recruit APSIPA new e-members.

Dr Hang Yuan successfully passed his defense on Jan 21st and becomes the 120th graduate of MCL. The title of Dr Hang’s thesis is “Modeling and Optimization of Energy-Efficient Delay-Constrained Video Sharing Servers”. The committee was pleased with Dr Hang’s strong mathematical skills in problem formulation, system modeling and analysis. Congratulations to Dr Hang’s graduation.
