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 [...]
