چکیده

We present a comprehensive evaluation of performance of visual feature representations for MediaEval 2011 Violent Scenes Detection Task. As for global features, color moments, color histogram, edge orientation histogram, and local binary patterns are used. As for local features, keypoint detectors such as Harris Laplace, Hessian Laplace, Harris Affine, Dense Sampling are used to extract keypoints and SIFT and COLOR SIFT are used as descriptor of the region around these keypoints. The results obtained by our runs are presented. The demo is available at: http://satoh-lab.ex.nii.ac.jp/users/ledduy/Demo-MediaEval

NII, Japan at MediaEval 2012 Violent Scenes Detection Affect Task

We present a comprehensive evaluation of performance of shot-based visual feature representations for MediaEval 2012 Violent Scenes Detection Affect Task. In spite of using keyframe-based as last year, we try to apply shot-based features using the global features (color moments, color histogram, edge orientation histogram, and local binary patterns) for violent scenes detection. Besides that, w...

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 comb...

The MediaEval 2011 Affect Task: Violent Scenes Detection in Hollywood movies

This paper provides a description of the MediaEval 2011 Affect Task: Violent Scenes Detection. This task derives directly from a Technicolor use case which aims at easing a user’s selection process from a movie database. This task will therefore apply to movie content. We provide some insight into the Technicolor use case, before giving details on the task itself. Dataset, annotations, and eval...

NII-UIT at MediaEval 2014 Violent Scenes Detection Affect Task

Violent scene detection (VSD) is a challenging problem because of the heterogeneous content, large variations in video quality, and semantic meaning of the concepts. The Violent Scenes Detection Task of MediaEval [1] provides a common dataset and evaluation protocol thus enables a fair comparison of methods. In this paper, we describe our VSD system used in MediaEval 2014 and briefly discuss th...
