Abstract:

We basically use a Bag-of-Words framework. We compute the improved dense trajectories to compute Fisher vectors that serve as features. Using the training videos, we compute a mapping function which we conjecture to contain the principal information about each action. Given a temporally untrimmed video, we project it’s feature along this mapping. The transformed features are passed to 1-vs all SVM classifiers framework to get the prediction score of each actions in the given video clip.
