dc.description.abstract | The proposed method consists of three parts: features extraction, the
use of bag of words and classification. For the first stage, we use the STIP
descriptor for the intensity channel and HOG descriptor for the depth channel,
MFCC and Spectrogram for the audio channel. In the next stage, it was
used the bag of words approach in each type of information separately. We
use the K-means algorithm to generate the dictionary. Finally, a SVM classi
fier labels the visual word histograms. For the experiments, we manually
segmented the videos in clips containing a single action, achieving a recognition
rate of 94.4% on Kitchen-UCSP dataset, our own dataset and a
recognition rate of 88% on HMA videos. | |
