|1. (WO2018201551) FACIAL IMAGE FUSION METHOD AND APPARATUS AND COMPUTING DEVICE|
|Applicants:||XIAMEN HOME MEITU TECHNOLOGY CO., LTD.
|Title:||FACIAL IMAGE FUSION METHOD AND APPARATUS AND COMPUTING DEVICE|
A facial image fusion method and apparatus and a computing device. The method is applicable to fusing a face from a target image with a face in a material image, and comprises the steps: separately calculating a 3D model of a face in a material image and a 3D model of a face in a target image as a first 3D model and a second 3D model (S210); separately calculating a first projection matrix and a second projection matrix of the first 3D model and the second 3D model projected onto a plane (S220); calculating, according to the first 3D model and the first projection matrix, first texture coordinates of the face in the material image (S230); calculating, according to the second 3D model and the second projection matrix, second texture coordinates of the face in the target image (S240); correspondingly replacing the first texture coordinates with the second texture coordinates to obtain a reconstructed facial image of the target image (S250); and fusing the reconstructed facial image of the target image with the material image to generate a fused image (S260).
