Abstract: Embodiments of the present disclosure relate to an expression driving method and apparatus, a device, and a medium. The method includes: obtaining a target image, and recognizing an expression of a target object in the target image to obtain at least one expression coefficient; extracting an expression coefficient to be processed from the at least one expression coefficient, and determining an initial left expression coefficient and an initial right expression coefficient in the expression coefficient to be processed; generating a target left expression coefficient and a target right expression coefficient based on a similarity between the initial left expression coefficient and the initial right expression coefficient; and driving a virtual character to show a corresponding expression based on the target left expression coefficient and the target right expression coefficient.
