Embodiment Construction

[0039] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0040] The present invention aims at the problem that human facial expressions synthesized by the existing three-dimensional expression synthesis method lack authenticity, and provides an expression synthesis method with dynamic texture details.

[0041] like figure 1 As shown, the expression synthesis method with dynamic texture details provided by the embodiment of the present invention includes:

[0042] S101, obtaining the face model of the target object, and the displacement of the bone point movement when synthesizing different expressions;

[0043] S102, using the wrinkle normal map to add wrinkles to the face model;

[0044] S103, acquiring the target expression to be synthesized, and initially synthesizing the target expression by moving the p...

Abstract

The invention provides an expression synthesis method with dynamic texture details, which can improve the authenticity of a three-dimensional facial expression. The method comprises the following steps: acquiring a face model of a target object and the displacement of skeleton point movement when different expressions are synthesized; adding wrinkles to the face model by using the wrinkle normal map; obtaining a target expression needing to be synthesized, moving the position of the skeleton point according to the target expression needing to be synthesized and the determined displacement amount needing to be moved of the skeleton point when different expressions are synthesized, and preliminarily synthesizing the target expression; and according to the displacement of the skeleton points,changing the apparent, implicit and depth of wrinkles of the face model to obtain a target expression with wrinkle textures. The invention relates to the field of face recognition.

Description

technical field [0001] The invention relates to the field of face recognition, in particular to an expression synthesis method with dynamic texture details. Background technique [0002] As an important feature of individual recognition, the face is the most expressive part of the human body. In human communication, it conveys a wide range of information, such as emotions and psychological states. The emotional state of a person can be observed through facial expressions, and the physiological state of a person can also be inferred. [0003] With the rapid development of computer technology, expression synthesis technology has attracted more and more researchers' attention in the fields of graphics and image processing, computer-aided design, and human-computer interaction. It has important uses in interaction, film production, etc. [0004] With the advancement of technology, more and more people are focusing on expression synthesis based on 3D face models. The essence o...
