Problems solved by technology

[0004] However, the above two methods have all undergone geometric changes in the final image of the region used; making the image shape of the first face region and the second face region slightly different will not be able to recognize the final composite image. Which region provides the content used, and it is a basic requirement to keep the information unchanged in some applications; due to such technical defects, this type of method can only be used for entertainment applications

specific Embodiment approach

[0105] Embodiment 4 of the present invention provides a specific implementation of the global deformation processing module 30 in the replacement system of the above human face image, and the global deformation processing module 30 specifically includes the following content:

[0106] The geometric deformation model establishing unit is configured to establish a geometric deformation model by applying affine transformation in the global deformation correction method according to the feature points of the first human face area and the second human face area.

[0107]It can be understood that the affine transformation method is not the only transformation method used in this embodiment, and any method in the global deformation correction method can realize the geometric deformation model establishment unit to the second face area mask adjustment unit in this embodiment transformation process.

[0108] The global deformation processing unit is used to determine the affine transfo...

Embodiment approach

[0127] Embodiment 6 of the present invention provides a specific implementation of the replacement reference image acquisition module 50 in the above-mentioned human face image replacement system, and the replacement reference image acquisition module 50 specifically includes the following content:

[0128] The reference image acquisition unit of the second human face area is used to replace the deformed first human face area with the deformed second human face area, and the replaced area is the mask of the deformed first human face area and The intersection area of ​​the masks of the deformed second face area is used to obtain a reference image including the second face area.

[0129] A naturalized fusion processing unit, configured to perform naturalized fusion processing on the second human face area in the reference image including the second human face area.

[0130] Use the second face area to replace the first face area of ​​the deformed reference image, and the second ...

Abstract

The invention provides a replacement system of a face image. The system comprises a feature point information acquiring module, a foreground segmentation processing module, a global deformation processing module, a local deformation processing module, and an obtaining module. The feature point information acquiring module being in communication connection is used for acquiring feature points in afirst face region and a second face region and location information of the feature points; the foreground segmentation processing module is used for carrying out foreground segmentation on the first face region and the second face region; the global deformation processing module is used for carrying out global deformation processing on a replaced image; the local deformation processing module is used for carrying out local deformation processing on the first face region and a region adjacent to the first face region; and the obtaining module is used for replacing the deformed first face regioninto the deformed second face region to obtain a reference image. During the replacement process, the reference face image for replacement is changed to the lowest extent on the premise that the facefeature of the replaced image does not change, so that the naturalization degree of the face image after replacement is improved and no synthesis trace is watched by naked eyes.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a human face image replacement system. Background technique [0002] With the development of intelligent equipment in today's society, image processing has become an indispensable part of people's life. Whether it is professional image processing at work or entertainment image processing in life, the most important image processing method is One is to replace the face area in the image to obtain the image after replacing the face required for work or entertainment, so that the processing method of the replaced image can be used to accelerate the selection of virtual experience and save face image synthesis The cost and entertainment of enhancing the fun composition of images. [0003] At present, there are mainly two ways to replace the face area in the image. The first way is to extract the feature point set of the first face area image and the corresponding "cutout ar...
