- Abstract:
-
A drawback of the human interaction recognition algorithm based on a convolutional neural network (CNN) is that the extracted depth features cannot effectively represent the characteristics of interaction sequences. Instead, this paper proposes a human interaction recognition and prediction algorithm based on deep learning, by combining the Long Short-Term Memory (LSTM) network with the CNN model. In the process, video images of unknown action categories of different time lengths are sent to a trained CNN model to extract the depth features. The depth features are then sent to a trained LSTM model to complete the recognition and prediction of the interaction behavior. When tested on the UT-interaction human interaction behavior dataset, the algorithm demonstrates a 92.31% correct human interaction recognition rate and can complete the preliminary prediction of unknown actions.
