Abstract
In order to solve the problems of insufficient facial expression feature extraction and large parameter amount in some convolutional neural networks, a facial expression recognition algorithm based on multi-feature fusion is proposed. This method first modifies the residual block in the ResNet network, reduces the amount of network parameters and uses pre-activation to reduce the error rate. After that, the features extracted by the improved ResNet network are fused with the features extracted by the VGG network after the cut layer, and the network model P-ResNet-VGG is obtained. The loss function uses the cross entropy loss function. This model has been extensively tested on the FER2013 and JAFFE datasets. The experimental results show that this model has improved accuracy on the expression data set than other models, and it has a significant effect on the FER2013 and JAFFE data sets.
