Embodiment 1

[0063] The face image processing method based on grid deformation optimization provided by the present invention can be applied in a terminal, and the terminal can process the pose face image through the face image processing method based on grid deformation optimization provided by the present invention, Convert pose face images to frontal face images. Such as figure 1 As shown, in one embodiment of the face image processing method based on grid deformation optimization, the steps include:

[0064] S100. Acquire a first feature lattice of a pose face image and a second feature lattice of a predicted frontal face image corresponding to the pose face image.

[0065] In this embodiment, the front face image represents a face image facing straight ahead, and the pose face image is a face image that is not a front face image. When it is necessary to convert the pose face image into a front face image, first obtain the pose face The first feature lattice of the image, the first f...

Embodiment 2

[0126] Based on the above embodiments, the present invention also provides a corresponding terminal, such as Figure 8 As shown, the terminal includes a processor 10 and a memory 20 . Understandably, Figure 8 Only some components of the terminal are shown, but it should be understood that implementation of all illustrated components is not required, and more or fewer components may be implemented instead.

[0127] The storage 20 may be an internal storage unit of the terminal in some embodiments, such as a hard disk or memory of the terminal. In other embodiments, the memory 20 may also be an external storage device of the terminal, such as a plug-in hard disk equipped on the terminal, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD ) card, flash memory card (Flash Card), etc. Further, the memory 20 may also include both an internal storage unit of the terminal and an external storage device. The memory 20 is used to store application sof...

Embodiment 3

[0174] The present invention also provides a storage medium, in which one or more programs are stored, and the one or more programs can be executed by one or more processors, so as to realize the face optimization based on mesh deformation as described above The steps of the image processing method.

Abstract

The invention discloses a face image processing method based on grid deformation optimization, a terminal and a storage medium. The face image processing method comprises steps of: acquiring an attitude face image, and acquiring a first characteristic dot matrix of the attitude face image and a second characteristic dot matrix of a predicted front face image corresponding to the attitude face image, wherein the first characteristic dot matrix comprises first characteristic points, and the second characteristic dot matrix comprises second characteristic points; respectively constructing a firstgrid network corresponding to the attitude face image and a second grid network corresponding to the predicted front face image; and optimizing the position of each first feature point and the firstgrid network according to the second grid network and the second feature dot matrix, and processing the attitude face image into a front face image. According to the face image processing method, theattitude face image is converted into the front face image, so that the face recognition technology can recognize the attitude face image, and the performance of a face recognition system is improved.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a face image processing method based on grid deformation optimization, a terminal and a storage medium. Background technique [0002] Face recognition technology is widely used in various fields, but the current face recognition technology is often limited to frontal face (face facing the front) recognition, which makes the recognition efficiency of the face recognition system low. [0003] Therefore, the prior art still needs to be improved and improved. Contents of the invention [0004] In view of the above-mentioned defects of the prior art, the present invention provides a face image processing method, terminal and storage medium based on grid deformation optimization, aiming to solve the problem of low recognition efficiency of face recognition technology in the prior art. [0005] In order to solve the problems of the technologies described above, the technical scheme...
