Embodiment Construction
[0063] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0064] figure 1 The block diagram of this system mainly includes:
[0065] Step 1: preprocessing of video sequences;
[0066] Step 2: Using spatio-temporal convolutional neural network to extract spatio-temporal features of video clips;
[0067] Step 3: Deep fusion of spatio-temporal features extracted from video clips using deep belief network;
[0068] Step 4: Use the average pooling method to obtain the global features of the video sequence;
[0069] Step 5: Use the support vector machine to realize the expression recognition of the video sequence, and output the recognition result.
[0070] One, the realization of each step of this system block diagram, concrete expression is as follows in conjunction with embodiment:
[0071] (1) Preprocessing of video sequences
[0072] From the RML video sequence expression databa...
