The invention provides a diversified face
image synthesis method and
system. The method comprises the following steps: acquiring a source face picture, a target face picture and attribute tag information; according to the source face picture, the target face picture and the
face synthesis network model, obtaining a realistic face picture with a source face expression, a target
face identity feature and a specified attribute, wherein the
face synthesis network model comprises a face feature point generator and a geometry-attribute
perception generator; the face feature point generator is used for extracting feature points of a source face and a target face as face geometric feature information, extracting expression information from the face geometric feature information, and migrating the expression information of any source face to the target face in a
potential space; and the geometry-attribute
perception generator is used for correspondingly extracting identity features and specified attribute information from the target face and the
label respectively, and generating a realistic face picture with a source face expression, the target
face identity features and specified attributes in combination with the expression information.
