Modeling Visual Signals for Human and Machine Uses

Speaker: Prof. Weisi L.Lin , Nanyang Technological University, Singapore

Abstract: This talk firstly discusses how to model various visual signals (images, videos, graphics, 3D point clouds, and so on) for humans as the ultimate users. Since humans have developed unique characteristics in perception over the long evolution, effective perceptual signal modeling, processing and evaluation facilitate meaningful optimization of system performance and utility of available resources (bandwidth, memory, battery, computation, device cost/size, etc). The related topics include visual attention/saliency, just-noticeable difference (JND), quality of experience (QoE), and different application scenarios.
Machines are expected to become the ultimate users for a rapidly increasing amount of visual signals in this AI era, and therefore as the second part of the talk, we will investigate into the said concepts to be extended with machine tasks, including early examples of machine- oriented JND, and saliency and quality models for 3D point clouds. Finally, possible further research directions will be highlighted, inclusive of exploration toward true multimedia that consists of hearing, smell, touch and even taste aspects as well.  

Biography: Weisi Lin is an active researcher in intelligent image processing, perception-based signal modelling and assessment, video compression, and multimedia communication. He had been the Lab Head, Visual Processing, in Institute for Infocomm Research (I 2 R),Singapore. He is a Professor in School of Computer Science and Engineering, Nanyang Technological University, where he also served as the Associate Chair (Research). 

Food Computing for Human and Planet Health

Speaker: Prof. Yoko Yamakata, The University of Tokyo, Japan

Abstract: This keynote introduces food computing technologies for human and planet health. First, let us focus on human health. We are developing RecipeLog and FoodLog Athl, smartphone applications that allow users to upload a photo of a meal, identify the name of the meal through image recognition, calculate nutritional values such as energy, protein, fat, and carbohydrates based on the recipe, and create a food log. Traditionally, dietary management for patients and athletes involved manual analysis by dietitians based on patients’ manual food records, but under and over-reporting, in addition to high human costs for analysis, has been problematic. Our experiments have shown that information obtained by our application is more accurate and at lower human cost than manual recording.
The latter part of the talk will introduce food computing for the planet’s health. In the process of producing food, earth resources are mined to obtain phosphate fertilizer and to extract fuel for breeding and transportation. By calculating the amount of this mining for each food ingredient, it was estimated that, for example, an average of 5.2kg of soil is mined to provide one serving of beef stew. Our goal is to visualize these facts in a way accessible to ordinary people and to change their behavior in making food choices better for all.

Invite Lecture 1: 3D Virtual Human Modeling for Mataverse Applications

Speaker: Prof. In Kyu Park, Inha University, Korea

Abstract: 3D virtual human modeling is the key element of metaverse applications where the gap between the applications’ demand and the level of the SoTA techniques exist. In this talk, I will first introduce the recent trend of 3D human modeling techniques in computer vision and graphics fields. Then, I will introduce the outcome of my recent project during the last 3 years. Finally I will provide the future anticipation of 3D human modeling techniques for metaverse applications.

Invite Lecture 2: FTV Standardization in MPEG Promoted by a Professor

Speaker: Prof. Masayuki Tanimoto, Nagoya University, Nagoya Industrial Science Research Institute, Japan

Abstract: FTV (Free-viewpoint Television) enables users to view a 3D scene by freely changing their viewpoint, as we do naturally in the real world. FTV is an ultimate 3DTV and ranks as the top of visual media. FTV is immersive media that integrate real and virtual worlds. FTV was realized by developing novel ray capture, processing and display technologies. I have been promoting FTV standardization in 3 phases since 2001. Most of MPEG members come from industry. However, many professors are working actively in MPEG. Moreover, some students are working actively. MPEG provide students with a very good opportunity to improve their skills and accumulate experiences. Here, I talk about my experience in MPEG and how a professor continues FTV activity for 20 years. My recent work on next-generation FTV is also mentioned.

Biography: Masayuki Tanimoto received the B.E., M.E., and Dr.E. degrees in electronic engineering from the University of Tokyo in 1970, 1972, and 1976, respectively. He worked at Nagoya University from 1976 to 2012. Currently, he is an Emeritus Professor at Nagoya University and a Senior Research Fellow at Nagoya Industrial Science Research Institute. He developed TAT (Time-Axis Transform) system for HDTV compression. TAT system became one of the two candidates for HDTV satellite broadcast system in Japan. He also developed FTV (Free-viewpoint Television). He has been promoting FTV standardization in MPEG. He was the president of the ITE (Institute of Image Information and Television Engineers). He is Honorary Member of the ITE, Fellow of the IEICE (Institute of Electronics, Information, and Communication Engineers) and IEEE Life Fellow. He received the ITE Distinguished Achievement and Contributions Award, the IEICE Achievement Award, and the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science, and Technology.

Invite Lecture 3: Toward Real World Metaverse

Speaker:  Jong-Il Park, Hanyang University, Korea

Abstract: Metaverse is emerging fast as a practical way of enriching our everyday lives as well as realizing the digital transformation. Metaverse phenomenon today is largely owing to the rise of experiential media and the rapid spread of a non-face-to-face society due to COVID-19. Metaverse can be divided into a pure virtual world-based one and a mixture of reality and virtuality. As the number of virtual world increases, the scarcity of the real world will become more prominent, and the real world-based metaverse will have more important industrial value. Real-world metaverse provides real-virtual convergence services in a wide area simultaneously to numerous users with various heterogeneous terminals. In this talk, various examples of real world metaverse are explained. Next, our latest research that implements the manipulation and transformation of the real world by the virtual world in real-time are introduced. This implies that the real world and the virtual world can interact symmetrically in both directions. Finally, the prospects and promotion strategies of real-world metaverse are discussed.
