[0028] The present invention is based on the method for synthesizing facial expression images of a generative confrontation network, comprising the following steps:
[0029] Step 1, obtain the data of facial expressions;
[0030] Step 2, preprocessing the expression data set, first obtain the key point information of the face image, then cut the image into a uniform size according to the key point information, and divide it into training data and test data, and divide the training data according to different expression strengths Manually divided into different categories;
[0031] Step 3, constructing a generative confrontation network, and adding the discrimination information of expression strength and the sequence and correlation information between different strengths to the generative confrontation network;
[0032] Step 4, use the preprocessed expression data to train and test the generative confrontation network, adjust the parameters of the generative confrontation ne...
Embodiment 1
[0056] This embodiment takes CK+ (http: / / www.consortium.ri.cmu.edu / ckagree / ) and MUG (https: / / mug.ee.auth.gr / fed / ) data sets as examples for the present invention based on The face expression image synthesis method of generative confrontation network is researched, and the specific implementation steps are as follows:
[0057] Step 1. Download the facial expression sequence dataset from CK+ (http: / / www.consortium.ri.cmu.edu / ckagree / ) and MUG (https: / / mug.ee.auth.gr / fed / ) as Experimental data.
[0058] Step 2. After the data is acquired, it is preprocessed. In this embodiment, two expressions of happiness and surprise are taken as examples to study the proposed algorithm. In the CK+ data set, there are very few expression data, and there are only some expression labels. In order to make full use of the data, it is necessary to additionally classify the unclassified happy and surprised expressions. In the MUG data set, each subject's single expression contains some repeated se...
