Abstract
The present disclosure relates to a method and an apparatus for generating a virtual expression, an electronic device, and a storage medium. The method includes: obtaining a face region in an original image to obtain a target face image; obtaining a first face coefficient for the target face image; performing time-domain correction on the template expression coefficient and/or the pose coefficient of the first face coefficient, to obtain a target face coefficient; and according to the target face coefficient, rendering an expression of the virtual character, to obtain the virtual expression.
Claims21
A method for generating a virtual expression, comprising:
- obtaining a face region in an original image to obtain a target face image;
- obtaining a first face coefficient for the target face image, wherein the first face coefficient comprises a template expression coefficient and a pose coefficient, wherein the template expression coefficient is used to represent a degree of matching between a facial expression and each of one or more templates, and the pose coefficient is used to represent a rotation angle of a virtual character in three dimensions;
- performing time-domain correction on the template expression coefficient and/or the pose coefficient of the first face coefficient, to obtain a target face coefficient, wherein the target face coefficient is associated with a face coefficient for a previous original image before the original image;
- and
- according to the target face coefficient, rendering an expression of the virtual character, to obtain the virtual expression.
