FACIAL ACTION RECOGNITION MODEL TRAINING METHOD, FACIAL ACTION RECOGNITION METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM

摘要

A facial action recognition model training method, comprising: acquiring a facial action recognition data set, the facial action image recognition data set comprising multiple facial action images; inputting the facial action images in the facial action recognition data set into a preset multi-task convolutional neural network, and using the multi-task convolutional neural network to perform facial detection on the facial action images to obtain multiple corresponding facial feature images; according to a preset rule, respectively adding black blocks to the facial feature images, and using the obtained images as a training image set; inputting the training image set into a preset neural network to be trained in order to train the neural network to be trained, and using the trained neural network to be trained as a facial action recognition model.
