Dear Multimedia Community, This year we published an edited book including 11 tutorial chapters on topics at the heart of multimedia. These are authored by the first cohort of invited speakers at the inaugural 2015 SIGMM Rising Star workshop in Australia. I hope this is useful as education and introductory research materials for our community. Royalty income for the editor share will be donated to SIGMM. Best regards, Shih-Fu NEW BOOK: Frontiers of Multimedia Research edited by Shih-Fu Chang Published by ACM and Morgan & Claypool, 2018. book available at http://www.morganclaypoolpublishers.com/catalog_Orig/product_info.php?cPath=24&products_id=1159 and https://www.amazon.com/Frontiers-Multimedia-Research-Shih-Fu-Chang-ebook/dp/B07BNX38S8/ref=sr_1_1?ie=UTF8&qid=1535477642&sr=8-1&keywords=frontiers+of+multimedia+research Table of Contents PART I MULTIMEDIA CONTENT ANALYSIS Chapter 1 Deep Learning for Video Classification and Captioning Chapter 2 Audition for Multimedia Computing Chapter 3 Multimodal Analysis of Free-standing Conversational Groups Chapter 4 Encrypted Domain Multimedia Content Analysis Chapter 5 Efficient Similarity Search PART II HUMAN-CENTERED MULTIMEDIA COMPUTING Chapter 6 Social-Sensed Multimedia Computing Chapter 7 Situation Recognition Using Multimodal Data 159 Chapter 8 Hawkes Processes for Events in Social Media Chapter 9 Utilizing Implicit User Cues for Multimedia Analytics PART III MULTIMEDIA COMMUNICATION AND SYSTEMS Chapter 10 Multimedia Fog Computing: Minions in the Cloud and Crowd Chapter 11 Cloud Gaming Book Summary: The field of multimedia is unique in offering a rich and dynamic forum for researchers from "traditional" fields to collaborate and develop new solutions and knowledge that transcend the boundaries of individual disciplines. Despite the prolific research activities and outcomes, however, few efforts have been made to develop books that serve as an introduction to the rich spectrum of topics covered by this broad field. A few books are available that either focus on specific subfields or basic background in multimedia. Tutorial-style materials covering the active topics being pursued by the leading researchers at frontiers of the field are currently lacking. In 2015, ACM SIGMM, the special interest group on multimedia, launched a new initiative to address this void by selecting and inviting 12 rising-star speakers from different subfields of multimedia research to deliver plenary tutorial-style talks at the ACM Multimedia conference for 2015. Each speaker discussed the challenges and state-of-the-art developments of their prospective research areas in a general manner to the broad community. The covered topics were comprehensive, including multimedia content understanding, multimodal human-human and human-computer interaction, multimedia social media, and multimedia system architecture and deployment. Following the very positive responses to these talks, the speakers were invited to expand the content covered in their talks into chapters that can be used as reference material for researchers, students, and practitioners. Each chapter discusses the problems, technical challenges, state-of-the-art approaches and performances, open issues, and promising direction for future work. Collectively, the chapters provide an excellent sampling of major topics addressed by the community as a whole. This book, capturing some of the outcomes of such efforts, is well positioned to fill the aforementioned needs in providing tutorial-style reference materials for frontier topics in multimedia.
