METHOD AND APPARATUS FOR ESTABLISHING EXPRESSION RECOGNITION MODEL, AND COMPUTER DEVICE AND STORAGE MEDIUM

摘要

Disclosed are a method and apparatus for establishing an expression recognition model, and a computer device and a storage medium, belonging to the field of artificial intelligence. The method comprises: acquiring data of a plurality of first training images and data of a plurality of second training images (201); according to a feature value, acquiring clustering centers corresponding to data of a plurality of target images, and reference maps corresponding to the data of the plurality of target images (203); randomly extracting data of two target images of different reference maps as first input image data to obtain data of a plurality of first input images corresponding to the clustering centers; randomly extracting second input images corresponding to different clustering centers to obtain data of a plurality of second input images; and inputting the first input images, the second input images and the clustering centers corresponding to the first input images into an EmtionNet. In addition, the method also relates to blockchain technology. The data of the first training images and the data of the second training images can be stored in a blockchain, thereby improving the expression recognition accuracy.
