Abstract: A method for training a three-dimensional face reconstruction model includes inputting an acquired sample face image into a three-dimensional face reconstruction model to obtain a coordinate transformation parameter and a face parameter of the sample face image; determining the three-dimensional stylized face image of the sample face image according to the face parameter of the sample face image and the acquired stylized face map of the sample face image; transforming the three-dimensional stylized face image of the sample face image into a camera coordinate system based on the coordinate transformation parameter, and rendering the transformed three-dimensional stylized face image to obtain a rendered map; and training the three-dimensional face reconstruction model according to the rendered map and the stylized face map of the sample face image.

Abstract: An image processing method, an electronic device, and a storage medium are provided, relates to the field of augmented/virtual reality and image processing. A specific implementation solution may include: at least one first texture coefficient of a two-dimensional face image is acquired; a first texture image of the two-dimensional face image is generated based on the at least one first texture coefficient and a first texture base of the two-dimensional face image; the at least one first texture coefficient is determined to satisfy a first target condition based on the first texture image, and the first texture base is updated based on the first texture image, to obtain a second texture base; and in response to the second texture base converging successfully, three-dimensional reconstruction is performed on the two-dimensional face image based on the second texture base, to obtain a three-dimensional face image.

Abstract: A method of processing an image, an electronic device, and a storage medium. The method includes: determining a shape parameter, a texture parameter and a static wrinkle parameter for an object according to an input image; reconstructing a coarse reconstructed shape for the object by using the shape parameter, and computing a coarse reconstructed texture map for the object by using the texture parameter; determining a fine reconstructed shape and a fine reconstructed texture map according to the static wrinkle parameter, the shape parameter and the texture parameter; and performing a rendering process based on the coarse reconstructed shape, the coarse reconstructed texture map, the fine reconstructed shape and the fine reconstructed texture map, so as to obtain a coarse reconstructed image and a fine reconstructed image for the input image.
