Research on facial expression recognition of robot based on CNN convolution neural network

With the rapid development of artificial intelligence technology, as a direction of artificial intelligence research, the research of facial expression recognition has entered a new stage. Facial expression recognition has a wide range of applications in the fields of safe driving, medical treatment, human-computer interaction, etc. This paper studies a facial expression recognition method based on deep learning, which uses OpenCV to complete facial recognition. The facial expression recognition is realized through building and training CNN network by keras.
