چکیده

We present a comprehensive evaluation of shot-based visual and audio features for MediaEval 2013 Violent Scenes Detection Affect Task. To obtain visual features, we use global features, local SIFT features and motion features. For audio features, the popular MFCC is employed. Besides that, we also evaluate the performance of mid-level features which is constructed using visual concepts. We combined these features using late fusion. The results obtained by our runs are presented.
