FACIAL EXPRESSION SYNTHESIS METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM

A facial expression synthesis method is provided. The method includes obtaining a to-be-processed facial image of a target object, and processing the to-be-processed facial image by using a face-recognition operation, to obtain skin color information of the to-be-processed facial image; screening out a target expression-material image, from a plurality of expression-material images in an expression-material image library, matching the skin color information; extracting a region image corresponding to a target synthesis region in the target expression-material image; and performing Poisson fusion processing on the region image and the to-be-processed facial image to fuse the region image with the to-be-processed facial image, so as to obtain a target facial image of the target object.
