Bio: Prof. Junyu Dong received his BSc and MSc from the Department of Applied Mathematics at Ocean University of China in 1993 and 1999 respectively, and received his PhD in November 2003 in Heriot-Watt University, UK. He is currently a professor and the Dean of Faculty of Information Science and Engineering at Ocean University of China. His research interests include 3D underwater imaging and machine learning with applications in marine science. He has been the principal investigator of more than 10 research projects supported by NSFC and MOST. He has published more than 200 major journal and conference papers. Professor Junyu Dong has developed a series of high-resolution underwater 3D imaging systems, one of which achieves the highest accuracy in its category. These systems have been deployed to obtain 3D data of seabed topography, corals, underwater power cables, port seabed foundations, and various other underwater structures. He is the founding editor of Journal of Intelligent Marine Technology and Systems, and also a Chairman of Qingdao Chapter of the Association for Computing Machinery (ACM).

Bio: Prof. William Puech received the diploma of Electrical Engineering from the Univ. Montpellier, France (1991) and a Ph.D. Degree in Signal-Image-Speech from the Polytechnic National Institute of Grenoble, France (1997) with research activities in image processing and computer vision. He served as a Visiting Research Associate to the University of Thessaloniki, Greece. From 1997 to 2008, he has been an Associate Professor at the Univ. Montpellier, France. Since 2009, he is a full Professor in image processing at the Univ. Montpellier, France. His current interests are in the areas of image forensics and security for safe transfer, storage and visualization by combining data hiding, compression, cryptography and machine learning. He is head of the ICAR team (Image and Interaction) in the LIRMM and has published more than 50 journal papers and 160 conference papers and is currently Associate Editor for 4 journals (SPIC, SP, JVCIR and IEEE TCSVT) in the areas of image forensics and security and Senior Area Editor for IEEE TIFS. Since 2017 he has been the general chair of the IEEE Signal Processing French Chapter. He has been a member of the IEEE Information Forensics and Security TC between 2018 and 2020 and then again between 2022 and 2024. Since 2021 he has also been a member of the IEEE Image, Video and Multidimensional Signal Processing TC, and since 2025 member of the IEEE Multimedia Signal Processing TC.
