Embodiment 1

[0086] In this embodiment, taking the object having a three-dimensional structure as an example, the implementation of the method for generating a facial expression on an object without facial organs proposed in this embodiment is exemplarily described.

[0087] A method for generating facial expressions on an object without facial organs proposed in this embodiment includes:

[0088] Obtain a data model representing the surface shape of an object;

[0089] Obtain the initial data features of the facial organ model to be generated representing the facial organs. The initial data features include the shape features of the facial organs, the positional features of the facial organs, and the facial expression features. The shape features of the facial organs represent the face. The three-dimensional shape of the organ, the location feature of the facial organ represents the location of the facial organ, and the facial expression feature represents the facial expression;

Embodiment 2

[0096] In this embodiment, taking the object having a two-dimensional structure as an example, the implementation of the method for generating a facial expression on an object without facial organs proposed in this embodiment is exemplarily described.

[0097] A method for generating facial expressions on an object without facial organs proposed in this embodiment includes:

[0098] Obtain a data model representing the surface pattern of the object;

[0099] Obtain the initial data features of the facial organ model to be generated representing the facial organs. The initial data features include the contour features of the facial organs, the positional features of the facial organs, and the facial expression features. The contour features of the facial organs represent the face. The plane outline of the organ, the location feature of the facial organ represents the location of the facial organ, and the facial expression feature represents the facial expression;

Embodiment 3

[0106] In this embodiment, taking the object having a three-dimensional structure and having a material texture on the surface as an example, the implementation of the method for generating facial expressions on an object without facial organs proposed in this embodiment is exemplarily described.

[0107] A method for generating facial expressions on an object without facial organs proposed in this embodiment includes:

[0108] Obtain a data model representing the surface shape and material texture of the object;

[0109] Obtain the initial data features of the facial organ model to be generated to represent the facial organs. The initial data features include the shape features of the facial organs, the position features of the facial organs, and the facial expression features. The shape features of the facial organs represent the face The three-dimensional shape of the organ, the position feature of the facial organ represents the position of the facial organ, and the facial e...

Abstract

The invention relates to a method and device for generating a facial expression on an object without a facial organ, and the method comprises the steps: selecting a to-be-processed region on the surface of a data model for representing the object; Generating a face organ model representing a face organ in the to-be-processed area; And migrating the facial expression to the generated facial organ model. According to the technical scheme provided by the embodiment of the invention, the facial expression is formed on the data model for representing the object without the facial organ, so that theobject without the facial organ is endowed with the anthropomorphic expression, the application scene of facial expression simulation is widened, and the user experience is enhanced.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and a device for generating human facial expressions on an object without facial organs. Background technique [0002] Facial expression recognition and facial expression transfer are relatively common technologies at present. On this basis, in order to achieve anthropomorphic effects, there have also been applications for giving or transferring expressions to animals. The above-mentioned technologies have in common that facial expressions are generated based on existing facial features through facial expression recognition, facial expression transfer and other technologies. The application scenarios are limited and the user experience is poor. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems of limited application scenarios and poor user experience caused by the need to generate facial expressions on exist...
