Embodiments of the present application provide a method, device and electronic equipment for generating a face image and its model training. The method for generating a human face image includes: acquiring a first image including human face coordinate information; based on the first image and a principal component analysis base corresponding to the human face coordinate information, obtaining position parameters of human face local features in the first image; The mask normal map generated based on the position parameters and the background image corresponding to the mask normal map are synthesized to obtain a second image; a texture image corresponding to the second image is generated by generating an adversarial network, so as to compare the second image based on the texture image Carry out texture enhancement, obtain the target face image that contains face feature normal information and face texture information, the method of this embodiment has not only guaranteed the accuracy of face features, but also improved the relationship between face texture information and normal information. Consistency, thereby ensuring the details and authenticity of face images.
Description
technical field [0001] The present application relates to the field of computer technology, in particular, to a method, device, computer-readable medium and electronic equipment for generating face images and model training thereof. Background technique [0002] In some 3D application scenarios, it is necessary to shape the facial image of the human face. At the same time, accurate and subtle facial texture information is required during the facial shaping process, such as key information such as the pores, eyebrows, and beard of the human face. Generally, the face is shaped by the facial normal map, but the normal map obtained in this way is blurred and the details of the facial texture information are not clear, or the normal map and the face texture information are inconsistent, which reduces the effect of facial shaping. . Contents of the invention [0003] Embodiments of the present application provide a method, device, computer-readable medium, and electronic equipm...
