Author Description

With great pleasure, we welcome you to join ACM Multimedia 2020, the 28th ACM International Conference on Multimedia. ACM Multimedia is the premier international conference series in the area of multimedia within the field of computer science. Since 1993, ACM Multimedia has been bringing together worldwide researchers and practitioners from academia and industry to present their innovative research and to discuss recent advancements in multimedia. This year's conference, for the first time in the history, will be running as an online large-scale meeting due to COVID-19. Face-to-face gatherings have been replaced by all-hands live sessions, parallel live question-answering (Q&A) sessions, and presentations from the authors via pre-recorded videos. However, the distance needed to prevent the spreading of the virus does not cool down enthusiasm in participants, presenters, chairs, reviewers, and volunteers. Under today's challenging circumstance, we are pleased that we are still able to deliver the most cutting-edge research results, covering the latest findings in the field, for which the ACM Multimedia conference series is widely known. From some different perspectives, virtual conference is probably even better. All the videos can be previewed online before the start of main conference events, and within 10 days, you can replay them as many times as you would like to. During conference days, you can join and jump virtually among as many Q&A sessions as possible. Furthermore, for each Q&A session, there will be a mirrored one after 10 hours for you to join in case your time zone is not suitable to participate for the first one. We would like to urge the participants to check the FAQ to plan your conference days in the best and most comfortable way. This year we are honored to welcome two distinguished keynote speakers. The opening keynote will be delivered by Dr. Shuicheng Yan, who is currently CTO of YITU Tech, and was previously a Professor at the National Universi
