Abstract:

The traditional interface performance is not clear, and the programming statements are tedious. We design the interface of facial expression recognition system based on the NI company LabVIEW software, and discuss the key problems in the design of facial expression recognition system, then use efficient Matlab processing software engineering, to extract expression image feature, using the theory of discrete wavelet algorithm and the of flexible template matching algorithm is used to identify the emotion. The experimental results show that the design based on LabVIEW facial expression recognition system uses the LabVIEW software simple statement to design a clear interactive interface, and the recognition rate can reach more than 85%.

Key words: facial expression, emotion recognition, wavelet algorithms, flexible template matching, interface design
