The present disclosure relates to the technical field of image processing, in particular to the technical field of artificial intelligence such as computer vision and deep learning, and specifically to a method and an apparatus of generating a virtual idol, and an electronic device.
A virtual idol is a character image that is made by means of painting, animation, and the like, and performs activities in a virtual scenario such as the Internet or in a real-world scenario, but does not exist in a form of a physical entity.
The present disclosure provides a method and an apparatus of generating a virtual idol, and an electronic device, which may generate, in a targeted manner, a virtual idol for a scenario where a target object is endorsed, so that the virtual idol may subsequently be used to endorse the target object.
According to an aspect of the present disclosure, a method of generating a virtual idol is provided, and the method of generating a virtual idol may include:
According to another aspect of the present disclosure, an electronic device is provided, and the electronic device may include:
According to another aspect of the present disclosure, a non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by one or more processors of an electronic device, cause the electronic device to perform:
The accompanying drawings are used for a better understanding of the solutions, and do not constitute a limitation on the present disclosure. In the accompanying drawings:
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, where various details of the embodiments of the present disclosure are included to facilitate understanding, and should be considered as exemplary. Therefore, those of ordinary skill in the art should be aware that various changes and modifications can be made to the embodiments described herein, without departing from the scope and spirit of the present disclosure. Likewise, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.
In the embodiments of the present disclosure, “at least one” refers to one or more, and “a plurality of” refers to two or more. “And/or” describes an access relationship between associated objects, and represents that three relationships may exist. For example, A and/or B may represent the following three cases: only A exists, both A and B exist, and only B exists, where A and B may be singular or plural. In the written description of the present disclosure, the character “/” generally indicates an “or” relationship between the associated objects. In addition, in the embodiments of the present disclosure, the terms “first”, “second”, “third”, “fourth”, “fifth”, and “sixth” are used merely to distinguish the contents of different objects, and have no other special meaning.
When a virtual idol is used to replace a real person to perform an activity, taking a product endorsement scenario as an example, how to generate the virtual idol in the product endorsement scenario to replace the real person with the virtual idol to endorse a product is an urgent problem to be solved by those skilled in the art.
The technical solutions provided in the embodiments of the present disclosure may be applied in scenarios such as a product endorsement, a live product sale, and even a film and television performance. Taking the application in the product endorsement as an example, using a virtual idol to perform the product endorsement requires the virtual idol to be generated first. The virtual idol is a character image that is made by means of painting, animation, and the like, performs activities in a virtual scenario such as the Internet or in a real-world scenario, but does not exist in a form of a physical entity.
In related arts, during generation of a virtual idol, a 3D modeling technique is usually used to design a 3D virtual image firstly; then a professional motion capture device is used to optically capture motions and expressions of a real person; and lastly the motions and expressions optically captured are mapped to the 3D virtual image to drive the virtual idol to performs the product endorsement.
However, when the existing method of generating a virtual idol is used, that is, the 3D modeling technique is used to design the 3D virtual image, the design of the virtual idol is complex, and personification thereof is poor. Furthermore, when optical capture is used to capture the motions and expressions of the real person, an inertia capture has a poor accuracy, and is vulnerable to geomagnetic interference.
To improve the generation of the virtual idol, it is possible to select, in a targeted manner based on feature information of a target object requiring endorsement, a virtual face and a motion video that match with feature information; and use a face fusion technique to fuse the virtual face and a facial image in the motion video, so that, in a targeted manner, the virtual idol for a scenario where the target object is endorsed may generated and the virtual idol may subsequently be used to endorse the target object. In addition, when the virtual idol is used to endorse the target object, using the face fusion technique to generate the virtual idol may further effectively solve the problems existing in the generation of the virtual idol in the prior art, that a 3D virtual image has a complex design, a poor personification, and a poor accuracy of inertia capture, and that the inertia capture is vulnerable to a geomagnetic interference.
Based on the above technical concept, the embodiments of the present disclosure provide a method of generating a virtual idol. The method of generating a virtual idol according to the present disclosure will be described in detail below through some embodiments. It can be understood that the following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
S101: feature information of a target object is obtained.
Exemplarily, the feature information may include suitable population of the target object, a type of the target object, and the like, which may be set according to practical needs. For example, when the target object is sports shoes for children, the feature information includes that the suitable population is children, and that the type is a sports type. When the target object is a product for the elders, the feature information may include that the suitable population is the elders, and the type is a health care type.
Exemplarily, the feature information of the target object may be obtained by directly receiving feature information of the target object input by a user, by receiving feature information of the target object sent by another electronic device, or by obtaining feature information of the target object from a local storage, or by using another method, which may be set according to practical needs. Herein, the embodiments of the present disclosure are described by taking the above three methods as examples, which does not represent that the embodiments of the present disclosure are limited thereto.
After the feature information of the target object is obtained, to generate a virtual idol aiming at a scenario where the target object is endorsed, the feature information of the target object may be used as a generation basis, a target virtual face matching with the feature information may be determined from a preset face material library in a targeted manner, and a target motion video matching with the feature information may be determined from a preset motion video library, so that the virtual idol for the scenario where the target object is endorsed may be generated based on the target virtual face and the target motion video, which means that S102 and S103 are performed:
S102: the target virtual face matching with the feature information is determined from the preset face material library, and the target motion video matching with the feature information is determined from the preset motion video library.
The face material library includes a plurality of virtual faces.
It can be understood that before the target virtual face matching with the feature information is determined from the preset face material library, the preset face material library needs to be established in advance. Exemplarily, when the face material library is established in advance, a face generation network model may be used to create a plurality of virtual faces having real idol temperaments, and then the preset face material library is established based on the plurality of virtual faces having real idol temperaments. It should be noted that when a new virtual face is obtained, the new virtual face may be used to update the preset face material library.
Exemplarily, a stylegan2 model, or another network model having a similar function, may be used as the face generation network model, which may be set according to practical needs. The embodiments of the present disclosure are described by taking the face generation network model being the stylegan2 model as an example, which does not represent that the embodiments of the present disclosure are limited thereto.
For example, the face generation network model is the stylegan2 model. When the stylegan2 model is used to create a plurality of virtual faces having good looks, a great number of images of real idols may be collected, and the great number of images of real idols may be used to train the initial stylegan2 model to obtain an optimized stylegan2 model; then, the optimized stylegan2 model may be used to generate the plurality of virtual faces having real idol temperaments. Exemplarily, with reference to
The motion video library includes a plurality of motion videos, where the motion videos are videos of users’ limb motions.
It can be understood that before the target motion video matching with the feature information is determined from the preset motion video library, the preset motion video library needs to be established in advance. Exemplarily, when the motion video library is established in advance, a photographing device, such as a camera, may be used to record a plurality of users’ motion videos, and the preset motion video library may be established based on the recorded plurality of users’ limb motions. It should be noted that when a new motion video is obtained, the new motion video may be used to update the preset motion video library.
After the feature information of the target object is used as the generation basis, the target virtual face matching with the feature information is determined from the preset face material library, and the target motion video matching with the feature information is determined from the preset motion video library, the following S103 may be performed:
S103: the target virtual face and a facial image in the target motion video are fused to generate the virtual idol corresponding to the target object.
The facial image in the target motion video may be understood as a facial image of a real person, namely, a user’s facial image in the target motion video.
Exemplarily, when the target virtual face and the facial image in the target motion video are fused, a face fusion technique may be used to fuse the target virtual face and the facial image in the target motion video, so as to generate the virtual idol.
As can be seen, in the embodiments of the present disclosure, during obtaining of the virtual idol, the feature information of the target object may be obtained, and then the feature information of the target object is used as the generation basis for the virtual idol, so that the target virtual face matching with the feature information may be determined from the preset face material library in a targeted manner, and the target motion video matching with the feature information may be determined from the preset motion video library; and then the virtual face and the facial image in the motion video are fused, which may generate the virtual idol aiming at the scenario where the target object is endorsed, so that the virtual idol may subsequently be used to endorse the target object.
Based on the above embodiment shown in
When the target virtual face matching with the feature information is determined from the preset face material library, exemplarily, a target virtual face type corresponding to the feature information may be determined first, and then based on the target virtual face type, the target virtual face is determined from the preset face material library.
Exemplarily, a virtual face type may be a youth type, a vivaciousness type, a tastefulness type, a dignity type, a beauty type, a handsomeness type, a sunshine type, and the like, which may be set according to practical needs. Herein, the embodiments of the present disclosure are described by taking these types as examples, which does not represent that the embodiments of the present disclosure are limited thereto.
Exemplarily, when the target object is sports shoes for children, and the feature information includes that the suitable population is children, and that the type is a sports type, the corresponding target virtual face type may be the youth type, the vivaciousness type, and/or the like; when the target object is a product for the elders, and the feature information includes that the suitable population is the elders, and that the type is a health care type, the corresponding target virtual face type may be the tastefulness type, the dignity type, and/or the like.
After the target virtual face type corresponding to the feature information is determined, the target virtual face may be determined from the preset face material library based on the target virtual face type. Exemplarily, in addition to the plurality of virtual faces, the face material library includes virtual face types corresponding to the virtual faces, and each virtual face type may be annotated on the corresponding virtual faces.
Exemplarily, there may be two cases of determining the target virtual face from the preset face material library based on the target virtual face type. One case is that when a virtual face corresponding to the target virtual face type is determined from the preset face material library based on the target virtual face type, that is, the number of virtual faces determined is one, the virtual face may be directly determined as the target virtual face; and
the other case is that when virtual faces corresponding to the target virtual face type is determined from the preset face material library based on the target virtual face type, that is, the number of virtual faces determined is more than one, and a plurality of virtual faces are determined based on the target virtual face type, one virtual face further needs to be selected from the virtual faces corresponding to the target virtual face type, and then is determined as the target virtual face.
Exemplarily, when the target virtual face is determined from the virtual faces corresponding to the target virtual face type, the following at least three possible implementations may be included.
In a possible implementation, one virtual face may be randomly selected from the virtual faces corresponding to the target virtual face type, and is determined as the target virtual face.
In another possible implementation, a virtual face having the highest historical frequency of selection may be determined from the virtual faces corresponding to the target virtual face type based on a historical frequency of selection of the virtual faces, and is determined as the target virtual face.
In still another possible implementation, when the target virtual face is determined from the virtual faces corresponding to the target virtual face type, the virtual faces corresponding to the target virtual face type may be displayed to a user, so that the user may select a desired virtual face from the displayed virtual faces according to needs; and in response to a selection instruction of the user among the virtual faces, the target virtual face is determined from the virtual faces.
As can be seen, compared with the first two possible implementations, such an implementation of displaying the virtual faces to the user, and in response to the selection instruction among the virtual faces, determining the target virtual face from the virtual faces takes the user’s needs into full consideration, which enables the selected target virtual face to more comply with the user’s needs.
It should be noted that in the embodiments of the present disclosure, when the target virtual face is determined from the virtual faces corresponding to the target virtual face type, the above three possible implementations are merely examples for illustration, and may be set according to practical needs.
As can be seen, in the embodiments of the present disclosure, when the target virtual face matching with the feature information is determined from the preset face material library, the target virtual face type corresponding to the feature information may be determined first, and then based on the target virtual face type, the target virtual face is determined from the preset face material library in a targeted manner. The target virtual face determined in this manner is more consistent with the feature information of the target object, and subsequently, the virtual idol for the scenario where the target object is endorsed may be generated in a targeted manner based on the target virtual face, so that the virtual idol may subsequently be used to endorse the target object.
In a process of generating the virtual idol, in addition to determining the target virtual face matching with the feature information from the preset face material library, it is further required to determine the target motion video matching with the feature information from the preset motion video library. The following describes in detail how to determine the target motion video matching with the feature information from the preset motion video library.
When the target motion video matching with the feature information is determined from the preset motion video library, exemplarily, a target costume type corresponding to the feature information may be determined first; and then based on the target costume type, the target motion video is determined from the preset motion video library.
Exemplarily, a costume type may be a sportswear type, a casual-wear type, a formal-wear type, and the like, which may be set according to practical needs. Herein, the embodiments of the present disclosure are described by taking these types as examples, which does not represent that the embodiments of the present disclosure are limited thereto.
Exemplarily, when the target object is sports shoes for children, and the feature information includes that the suitable population is children, and that the type is a sports type, the corresponding target costume type may be a sportswear type; when the target object is a product for the elders, and the feature information includes that the suitable population is the elders, and that the type is a health care type, the corresponding target costume type may be the causal-wear type.
After the target costume type corresponding to the feature information is determined, the target motion video may be determined from the preset motion video library based on the target costume type. Exemplarily, in addition to the plurality of motion videos, the motion video library may include costume types corresponding to motion videos, and each costume type may be annotated on the corresponding motion video.
Exemplarily, there may be two cases of determining the target motion video from the preset motion video library based on the target costume type. One case is that when a motion video corresponding to the target costume type is determined from the preset motion video library based on the target costume type, that is, the number of the motion videos determined is one, the motion video may be directly determined as the target motion video; and
the other case is that when motion videos corresponding to the target costume type is determined from the preset motion video library based on the type costume type, that is, the number of the motion videos determined is more than one and a plurality of motion videos are determined based on the target costume type, one motion video further needs to be selected from the motion videos corresponding to the target costume type, and then is determined as the target motion video.
Exemplarily, when the target motion video is determined from the plurality of motion videos corresponding to the target costume type, the following at least three possible implementations may be included:
In a possible implementation, one motion video may be randomly selected from the motion videos corresponding to the target costume type, and is determined as the target motion video.
In another possible implementation, a motion video having the highest historical frequency of selection may be determined from the motion videos corresponding to the target costume type based on a historical frequency of selection of the motion videos, and is determined as the target motion video.
In still another possible implementation, when the target motion video is determined from the motion videos corresponding to the target costume type, the motion videos corresponding to the type costume type may be displayed to the user, so that the user may select a desired motion video from the displayed motion videos according to needs; and in response to a selection instruction of the user among the motion videos, the target motion video is determined from the motion videos.
As can be seen, compared with the first two possible implementations, such an implementation of displaying the plurality of motion videos to the user, and in response to the selection instruction among the plurality of motion videos, determining the target motion video from the motion videos takes the user’s needs into fully consideration, which enables the selected target motion video to more comply with the user’s needs.
It should be noted that in the embodiments of the present disclosure, when the target motion video is determined from the plurality of motion videos corresponding to the target motion video type, the above three possible implementations are merely examples for illustration, and may be set according to practical needs.
As can be seen, in the embodiments of the present disclosure, when the target motion video matching with the feature information is determined from the preset motion video library, the target motion video type corresponding to the feature information may be determined first, and then based on the target motion video type, the target motion video is determined from the preset motion video library in a targeted manner. The target motion video determined in this manner is more consistent with the feature information of the target object, and subsequently, the virtual idol for the scenario where the target object is endorsed may be generated based on the target motion video in a targeted manner, so that the virtual idol may subsequently be used to endorse the target object.
Based on any one of the above embodiments, after the target virtual face matching with the feature information is determined from the preset face material library, and the target motion video matching with the feature information is determined from the preset motion video library, the target virtual face and the facial image in the target motion video may be fused to generate the virtual idol corresponding to the target object. For ease of understanding of how to fuse the target virtual face and the facial image in the target motion video to generate the virtual idol corresponding to the target object in the embodiments of the present disclosure, a detailed description will be made below through some embodiments shown in
