Abstract

We describe in this paper our approach for the Multi-modal gesture recognition challenge organized by ChaLearn in conjunction with the ICMI 2013 conference. The competition's task was to learn a vocabulary of 20 types of Italian gestures performed from different persons and to detect them in sequences. We develop an algorithm to find the gesture intervals in the audio data, extract audio features from those intervals and train two different models. We engineer features from the skeleton data and use the gesture intervals in the training data to train a model that we afterwards apply to the test sequences using a sliding window. We combine the models through weighted averaging. We find that this way to combine information from two different sources boosts the models performance significantly.
