Resumo

There are several aspects that may help in the characterization of an action being performed in a video, such as scene appearance and estimated movement of the involved objects. Many works in the literature combine different aspects to recognize the actions, which has shown to be superior than individual results. Just as important as the definition of representative and complementary aspects is the choice of good combination methods that exploit the strengths of each aspect. In this work, we propose a novel fusion strategy based on two fuzzy integral methods. This strategy is capable of generalizing other common operators, besides it allows more combinations to be evaluated by having a distinct impact in sets linearly dependent. Our experiments show that the fuzzy fusion outperforms the most commonly-used weighted average on the challenging UCF101 and HMDB51 datasets. (AU)
