Image face changing method and device, video face changing method and device, equipment and storage medium

Abstract

The embodiment of the invention discloses an image face changing method and device, a video face changing method an device, equipment and a storage medium. The image face changing method comprises thesteps: acquiring a second image used for executing face changing operation on a first image to be subjected to face changing, wherein the first image comprises a first face, and the second image comprises a second face; performing deformation processing on the first face in the first image to obtain a third image containing the deformed first face, wherein face key points of the deformed first face and the second face are aligned; obtaining a fusion mask, wherein the fusion mask has transparency; and replacing the deformed first face in the third image with the second face according to the transparency to obtain a target image after face changing of the first image. According to the embodiment of the invention, the color of the image after face changing is adjusted by calculating the pixel value through the transparency, image face changing is realized without Poisson fusion, the gradient of the image does not need to be calculated, the algorithm is simple, a natural face changing effect is obtained, and the image fusion speed and the image face changing efficiency are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular, to an image face-swapping method, a video face-swapping method, a device, a device, and a storage medium. Background technique [0002] With the popularity of video applications such as short videos and live broadcasts, editing video faces in videos has become a hot topic, and changing faces in videos is a very interesting and attractive function. Research and exploration on video face swapping It is also a hot topic in recent years. [0003] In the prior art, the Poisson fusion method is often used to replace the face in the video. The Poisson fusion method uses the Poisson equation to solve the optimal value of the pixel. While retaining the gradient information of the source image, it can also fuse the source image well. With the background of the target image, this method solves a Poisson equation according to the boundary conditions spec...
