Problems solved by technology

The above face-changing technology does not distort and deform the face area of ​​the original image according to the position of the feature points of the two face images to be changed.
[0003] Therefore, this face-changing technology can usually only process the frontal image of a human face, and if it is a non-frontal face image, the processing effect will be poor

Embodiment Construction

[0008] The face exchange method provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0009] figure 1 It is a flow chart of the face exchange method provided by the embodiment of the present invention.

[0010] refer to figure 1 , in step S101, identify the key parts of the human face, the key parts of the human face include the key parts of the first human face and the key parts of the second human face.

[0011] In step S102, the key parts of the first human face and the key parts of the second human face are located according to the human face model.

[0012] In step S103, calculate the motion vector field from the key parts of the first human face to the key parts of the second human face.

[0013] In step S104, deforming the first human face to the position of the second human face according to the motion vector field to obtain a deformed human face.

[0014] In step S105, naturalization pr...

Abstract

The present invention provides a face exchange method, comprising: identifying key positions of a face, the key positions consisting of key positions of a first face and key positions of a second face; positioning the key positions of the first face and the key positions of the second face according to a face model; calculating a motion vector field from the key positions of the first face to the key positions of the second face; deforming the first face to the position of the second face according to the motion vector field and then obtaining a deformed face; and performing a naturalization process of the deformed face. According to the invention, the faces may be quickly exchanged.

Description

technical field [0001] The invention relates to digital image processing technology, in particular to a face exchange method. Background technique [0002] The face-changing technology currently used is to manually mark the face area and the position of the feature point, and there is no automatic face recognition function; in the face-changing process, the original image is simply cut out according to the manually marked face area , and then placed into the target image. The above face-changing technology does not distort and deform the face area of ​​the original image according to the position of the feature points of the two face images to be changed. [0003] Therefore, this face-swapping technology can usually only process the frontal image of a human face, and if it is a non-frontal face image, the processing effect will be poor. Contents of the invention [0004] The human face exchange method provided by the present invention can realize rapid face exchange. ...
