Problems solved by technology

[0004] Face-changing based on deep learning requires users to upload images and videos to the server for processing. From a technical perspective, developers of the above user data can use them at will, and pose a great threat to users' personal privacy, and the cost of face-changing is high; while local The realized lightweight face change does not deal well with light, skin color, etc., and the traces of face change are obvious. When the shape of the facial features changes, it cannot be adjusted well

Abstract

The invention provides a video face changing method and device. The video face changing method comprises the steps of obtaining a to-be-processed image frame, performing key detection on a template image and a to-be-processed user image, adjusting key points to achieve alignment and superposition, migrating fusion of areas such as a face and skin color, restoring other parts, fusing a face contour mask image to a template, and performing replacement to obtain a face-changed image frame. The method can be realized locally, the privacy can be better protected, and the shape problems of light, skin color, five sense organs and the like are solved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video face changing method and device. Background technique [0002] With the development of AI technology and deep face-changing technology of artificial intelligence, the core of deep learning AI Deepfakes is to use the noise encoder to identify whether the image has undergone image transformation. In the fake video, it is necessary to perform image transformation processing on the face image of the person. To obtain multiple frames of the person's face image, and then replace the multiple frames of the person's face image with the person's face image in the original video to obtain a forged video, wherein the denoising encoder is based on the first sample person The face image and the second sample face image are obtained by training the self-encoder. [0003] There is another lightweight face-changing algorithm, whose core idea is not to use the method of ...
