The Grand Challenge was first presented as part of ACM Multimedia 2009 and has established itself as a prestigious competition in the multimedia community.

The finalists will be selected by a committee consisting of academia and industry representatives, based on novelty, presentation, and scientific interest of the approaches and, for the evaluation-based challenges, on the performance against the task. Preference is given to results that are reproducible by the research community, e.g. where the data and the source code is made available publicly. The finalists will be published in the proceedings and presented in a special event during the MM 2013 conference in Bareclona. Based on the presentation, winners will be selected for Grand Challenge awards.
