This chapter introduces a benchmark evaluation targeting the detection of violent scenes in Hollywood movies. The evaluation was implemented in 2011 and 2012 as an affect task in the framework of the international MediaEval benchmark initiative. We report on these 2 years of evaluation, providing a detailed description of the dataset created, describing the state of the art by studying the results achieved by participants and providing a detailed analysis of two of the best performing multimodal systems. We elaborate on the lessons learned after 2 years to provide insights on future work emphasizing multimodal modeling and fusion.
