Prof. Jin received the M.S. degree in communication and information system and the Ph.D. degree in information and communication engineering, both from Huazhong University of Science and Technology, Wuhan, China, in 2002 and 2005, respectively.
From 2004 to 2005, she was an Intern with the Internet Multimedia Group, Microsoft Research Asia, Beijing, China. From 2006 to 2008, she was a Postdoctoral Fellow with The Chinese University of Hong Kong. From 2008 to 2012, she was a Visiting Lecturer with the Information Technology Research Organization, Waseda University, Fukouoka, Japan. Since Mar. 2012, she has been with the Graduate School at Shenzhen, Tsinghua University, China, where she is currently a Professor in the Division of Information Science & Technology. Her current research interests include computational photography, power-constrained multimedia signal processing. She has published over 120 conference and journal papers.Dr. Jin is an IEEE Senior Member, and a member of SPIE and ACM. She is the chair of 3D video compression standard group of the Audio Video Standard Workgroup of China (AVS). She received Youth Top-notch Talent of Guangdong Special Support Program in 2017, the second prize of National Science and Technology Progress Award in 2016, the first prize of Guangdong science and technology award in 2015, and ISOCC Best Paper Award in 2010. She has served on many conference committees, e.g., PCM, VCIP, etc. and served as a reviewer for many transactions, e.g., IEEE TIP, TCSVT, etc. and international conferences, e.g., ICIP, ISCAS, ICME, etc.
Prof. Jin's research interests include computational photography and power constrained multimedia signal processing. Traditional cameras integrate light over the dimensions, such as directions, colors, temporal variations, by converting photons into electrons. The process preserves a subset of two dimensional, or some three-dimensional-time- varying information, while loses a huge amount of information in other plenoptic dimensions, e.g. directions of light rays, wavelength and polarizations.
Computational photography tries to make a big breakthrough in fundamental imaging theory and techniques to record the volumetric and contextual light field. In imaging theory, we research on theoretical imaging modeling and wave propagation analysis to improve the fidelity in recording the light field. Based on the theoretical researches, novel light field imaging systems are designed and built to reconstruction the light field with compact optical structure. Power constrained multimedia signal processing tries to process the high-dimensional light field information to realize novel applications like imaging through scattering media, light field stitching, depth estimation, refocusing, light field compression and light field rendering. During processing, not only the processing quality but also the implementation complexity is considered simultaneously to make the approaches be friendly to real applications.
