High-generalization face replacement method and device based on causal inference and electronic equipment

Abstract

The invention provides a high-generalization face replacement method and device based on causal inference and electronic equipment. The method comprises the following steps: determining a source face image and a target face image; inputting the source face image and the target face image into a face replacement model to obtain a face replacement image output by the face replacement model, wherein the face replacement model determines identity information representation of the source face image based on a causal effect of an expression attitude parameter of the target face image on the identity information, and performs face replacement based on the identity information representation and the perception information representation of the target face image; the face replacement model is obtained by training based on a sample source face image and a sample target face image. According to the method, the device, the electronic equipment and a storage medium provided by the invention, a high-quality and vivid face replacement image is obtained, so that the stability and generalization ability of a face replacement technology in different target scenes are improved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, and in particular, to a high-generalization face replacement method, device and electronic device based on causal inference. Background technique [0002] Face image identity replacement is a cutting-edge research problem in the field of computer vision and image generation. This technology has extremely important application value in the fields of virtual reality, film special effects, and game production. It has attracted widespread attention in academia and industry. Face image identity replacement, namely "face swap", replaces the identity information of the given target face image with the identity of the source face image, and keeps other contents in the image unchanged. [0003] At present, the difficulty of face-changing technology is to improve the generalization ability. In difficult scenarios where the source face image and the target face image are quite diffe...
