Abstract(in English) | Recognizing the activities of the construction vehicle helps to assess the skill of the workers or give a technical guidance to improve the workers' skill. Many research employ LSTM which can utilize long-term dependency for the activity recognition tasks. When we apply LSTM to the activity recognition tasks, we obtain multiple prediction results for data at the same frame. Conventional methods tend to employ an output only from the last frame of LSTM and others are disposed. Prediction accuracy can be improved by integrating these multiple outputs, but there is no current study. In this research, we tackle this issue by employing CRF. We'll show the proposed method overcomes the other methods throughout the experiment. |
