Abstract

The invention provides a face changing method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a source face image and a target face image; and inputting the source face image and the target face image into a face generator to obtain a face changing image output by the face generator, wherein the face generator is obtained by adversarial training with the face discriminator based on the sample image pair, the face discriminator is used for discriminating the authenticity of the sample image pair and the sample face-changing image thereof, and the sample face-changing image is obtained by the face generator by changing the face based on the sample image pair. According to the method and device, the electronic equipment and the storage medium provided by the invention, the face generator obtained by training in combination with the face discriminator has relatively high generalization performance, can adapt to any face image and has no identity limitation. Moreover, the training sample of the face generator does not need a large number of face images with the same identity, thereby effectively reducing the sample obtaining difficulty and obtaining cost, and further improving the application range of the face changing method.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a face changing method, device, electronic equipment and storage medium. Background technique [0002] Face swapping refers to transferring a face from a source face image to a target face image while retaining the attributes of the target face image, such as pose, expression, illumination, etc. [0003] In recent years, with the rapid development of face synthesis technology, face-changing technology has made great progress. Face swapping needs to separate the identity information from the attribute information, and then recombine them to get the swapped face image. [0004] The current face-changing method usually requires a large number of face images of the same identity to be modeled in order to realize the decoupling of identity information and attribute information. As a result, the current face-changing method is extremely difficult to apply to any face ...
