Vu Lam, Duy-Dinh Le, Shin’ichi Satoh, Duc Anh Duong · CEUR Workshop Proceedings · 2011
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
