Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings.
[0035] The invention discloses a video sequence expression recognition system based on self-attention enhanced CNN, such as figure 1 As shown, it mainly includes two parts: Feature-enhanced CNN (Feature-enhanced CNN) module and Self-attention mechanism (Self-attention) module; video sequence input feature-enhanced CNN module, feature-enhanced CNN module is used to obtain accurate video sequence The expression space information, the feature vector output by the feature enhancement CNN module is input into the self-attention mechanism module, and the self-attention mechanism module learns the internal dependencies of the video sequence, that is, the facial texture change relationship between frames due to facial muscle movement. , capture the internal structure, and then obtain the differentiated salient features, that is, the salient facial expression features presented...
