生成主观视觉上逼真的数字图像被视为进一步提高多媒体服务最终用户体验质量(QoE)的最终目标。人类的视觉系统能够感知各种各样的颜色、亮度和深度。然而，目前的传统成像技术无法捕捉和再现如此丰富的视觉信息。最近的一些研究创新使得解决多媒体系统中的这些瓶颈成为可能。因此，超高清、高帧率、高动态范围成像、光场、点云等新的多媒体信号处理领域应运而生。

10月29日上午，巴黎萨克雷大学的Frederic Dufaux教授应邀来作一场主题为《超真实感知沉浸式成像技术》的学术报告，并和科大的同学们深入讨论。

在报告中，Frederic Dufaux教授分享了超真实感知沉浸式成像技术领域现存的研究问题，并深入浅出地讲述了这一研究领域诸多技术细节。结合时代背景，Frederic Dufaux教授提出了对超真实感知沉浸式成像技术未来发展的展望。

在报告的最后，现场许多同学提出问题，和Frederic Dufaux教授积极地讨论。

Frederic Dufaux教授简介：

Frederic Dufaux is a CNRS Research Director at Université Paris-Saclay, CNRS, CentraleSupélec,Laboratoire des Signaux et Systèmes (L2S, UMR 8506), where he is head of the Telecom and Networking research hub.He received his M.Sc. in physics and Ph.D. in electrical engineering from EPFL in 1990 and 1994 respectively.

Frederic is a Fellow of IEEE. He was Vice General Chair of ICIP 2014, General Chair of MMSP 2018,and Technical Program co-Chair of ICIP 2019 and ICIP 2021. He served as Chair of the IEEE SPS Multimedia Signal Processing (MMSP) Technical Committee in 2018 and 2019. He was a member of the IEEE SPS Technical Directions Board from 2018 to 2021. He is Chair of the Steering Committee of ICME in 2022 and 2023. He was also a founding member and the Chair of the EURASIP Technical Area Committee on Visual Information Processing from 2015 to 2021. He was Editor-in-Chief of Signal Processing:Image Communication from 2010 until 2019.Since 2021, he is Specialty Chief Editor of the section on Image Processing in the journal Frontiers in Signal Processing.

Frederic is also on the Executive Board of Systematic Paris-Region, a European competitiveness cluster which brings together and drives an ecosystem of excellence in digital technologies and DeepTech.

He has been involved in the standardization of digital video and imaging technologies for more than 15 years, participating both in the MPEG and JPEG committees. He was co-chairman of JPEG 2000 over wireless (JPWL) and co-chairman of JPSearch. He is the recipient of two ISO awards for these contributions.

His research interests include image and video coding, 3D video, high dynamic range imaging, visual quality assessment, video surveillance, privacy protection, image and video analysis, multimedia content search and retrieval, and video transmission over wireless network. He is author or co-author of 3 books, more than 200 research publications (h-index=50, 10000+ citations) and 20 patents issued or pending.
