| Abstract(in English) | In this paper, we propose a robust online action recognition method based on boosted sequential classification. Our method utilizes boosting algorithm that is one of ensemble learning algorithms. This algorithm is also known as a feautre selector and has been utilized in the fields of image processing and natural language processing in recent years. Our method automatically and efficiently selects significant features for action recognition. Additionally, the method assumes interdependency between action labels based on Markov random fields. We evaluated our method to action recognition, such as walking and running, using motion capture data only with posture features. In the result, our method classified the actions more robustly than other methods that do not utilize interdependency between action labels. |
