ACM Multimedia is the premier international conference in the area of
multimedia within the field of computer science. Multimedia research
focuses on integration of the multiple perspectives offered by
different digital modalities including images, text, video, music,
sensor data, spoken audio. The conference covers four themes: Engaging
users with multimedia, Multimedia experience, Multimedia systems and
Understanding multimedia content.

We are calling for participation in this year’s Multimedia Grand
Challenges. The purpose of the challenges 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.
