Title:
METHOD AND APPARATUS FOR GENERATING EXPRESSION MODEL, AND DEVICE, PROGRAM AND READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/273113
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method and apparatus for generating an expression model, and a device, a program and a readable medium. The method comprises: adding, to an initial character model, a first deformation target corresponding to an expression model to be transferred, so as to obtain a first expression model, wherein the initial character model is a model without an expression; acquiring first boundary data corresponding to a first joint area of the first expression model; if the first boundary data indicates that the first joint area includes at least two boundaries, setting the first joint area to be in a non-deformation state, and then reversing the first expression model to obtain an intermediate expression model; and adding, to the initial character model without an expression, a second deformation target corresponding to the intermediate expression model, so as to obtain a second expression model. By means of the present application, a redundant action at a joint between an expression part and a non-expression part can be removed, thereby facilitating an improvement in the realness of a character making an expression.
