FACIAL ACTION UNIT RECOGNITION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM

摘要

A facial action unit recognition method and apparatus, an electronic device and a storage medium. Said method comprises: acquiring a first facial image to be recognized, uploaded by a terminal; using a pre-trained convolutional neural network model to perform face detection on said first facial image, to obtain position information of key facial points in said first facial image; using the position information of key facial points to perform face correction on said first facial image, to obtain a second facial image to be recognized; inputting said second facial image into a pre-trained facial action unit recognition model, and processing same by means of a main network part of the facial action unit recognition model, an attention mechanism and a fully-connected layer, so as to obtain a facial action unit recognition result of said first facial image; and outputting to the terminal the facial action unit recognition result of said first facial image. Said method is beneficial for improving the accuracy of recognition of a facial action unit in a facial image.
