Abstract: Technologies are described and recited herein for producing controllable synthesized images include a geometry guided 3D GAN framework for high-quality 3D head synthesis with full control on camera poses, facial expressions, head shape, articulated neck and jaw poses; and a semantic SDF (signed distance function) formulation that defines volumetric correspondence from observation space to canonical space, allowing full disentanglement of control parameters in 3D GAN training.

Abstract: Embodiments of the present disclosure disclose an image generation method, an apparatus, an electronic device, and a storage medium. The method includes: determining three-dimensional representations of preset areas in a target object according to a noise vector, wherein the three-dimensional representations are used to represent features of points in a space, and the preset areas have different size percentages in the target object; determining a three-dimensional mesh model in a target posture according to posture control parameters of the preset areas; sampling corresponding areas in the three-dimensional mesh model respectively according to camera poses for the preset areas, to obtain sampling points corresponding to the preset areas; determining target features corresponding to the sampling points according to the three-dimensional representations of the preset areas; and rendering the preset areas according to the target features, to generate target images, wherein the target images contain the target object in the target posture.

Abstract: A method for generating a multi-dimensional stylized image. The method includes providing input data into a latent space for a style conditioned multi-dimensional generator of a multi-dimensional generative model and generating the multi-dimensional stylized image from the input data by the style conditioned multi-dimensional generator. The method further includes synthesizing content for the multi-dimensional stylized image using a latent code and corresponding camera pose from the latent space to formulate an intermediate code to modulate synthesis convolution layers to generate feature images as multi-planar representations and synthesizing stylized feature images of the feature images for generating the multi-dimensional stylized image of the input data. The style conditioned multi-dimensional generator is tuned using a guided transfer learning process using a style prior generator.
