Overview of the Multimedia Grand Challenges 2022

The Multimedia Grand Challenge track was first presented as part of ACM Multimedia 2009 and has established itself as a prestigious competition in the multimedia community. The purpose of the Multimedia Grand Challenges is to engage the multimedia research community by establishing well-defined and objectively judged challenge problems intended to exercise the state-of-the-art methods and inspire future research directions. The key criteria for Grand Challenges are that they should be useful, interesting, and their solution should involve a series of research tasks over a long period of time, with pointers towards longer-term research. The 2022 edition of ACM Multimedia hosted 10 Grand Challenges covering all aspects of multimedia computing, from delivery systems to video retrieval, from video generation to audio recognition.
