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

摘要

A multitask facial action recognition model training method, comprising: collecting a facial action recognition data set; performing face detection and face alignment on facial action images in the facial action recognition data set to obtain key point label images; detecting angles of faces in the key point label images according to a preset standard image to obtain a multitask label image comprising an angle label; and inputting the multitask label image into a preset residual neural network to perform multitask training on the residual neural network, wherein the trained residual neural network is used as a multitask facial action recognition model.
