Abstract

Facial expression recognition is cutting-edge research in the field of computer vision, aiming to deepen the understanding of human emotions. With the popularity of social media and virtual interactions, there is an urgent need to accurately capture facial expressions to improve the user experience. In this paper, we summarize the research status of facial expression recognition, discuss the challenges faced by related technologies, and propose an improved VGG facial expression recognition method based on attention mechanism (AMVGG) to improve the recognition performance and promote the further development of this field. In this paper, it is proposed to embed multiple CBAM modules in the improved VGG network as the backbone network, and introduce deep attention center loss combined with softmax loss function to optimize the network. The experiments on the classical dataset FER2013 and RAF-DB achieved 73.81% and 88.76% accuracy, respectively, which were higher than those of other typical recognition algorithms.
