摘要This paper proposes a novel multi-modal gesture recognition framework and introduces its application to continuous sign language recognition. A Hidden Markov Model is used to construct the audio feature classifier. A skeleton feature classifier is trained to provided complementary information based on the Dynamic Time Warping model. The confidence scores generated by two classifiers are firstly normalized and then combined to produce a weighted sum for the final recognition. Experimental results have shown that the precision and recall scores for 20 classes of our multi-modal recognition framework can achieve 0.8829 and 0.8890 respectively, which proves that our method is able to correctly reject false detection caused by single classifier. Our approach scored 0.12756 in mean Levenshtein distance and was ranked 1st in the Multi-modal Gesture Recognition Challenge in 2013.
