Abstract: The present disclosure provides a virtual image generation method and apparatus, an electronic device and a storage medium, and relates to the field of artificial intelligence technologies such as augmented reality, computer vision and deep learning. A specific implementation scheme involves: acquiring base coefficients corresponding to key points of a target face based on a target face picture; generating a structure of a virtual image of the target face based on a mapping relationship of spatial alignment between a preset virtual model and a standard model, a base of the standard model and the base coefficients corresponding to the key points of the target face; and performing texture filling on the structure of the virtual image based on textures of the target face picture, to obtain the virtual image of the target face.

Abstract: A method of displaying an image, an electronic device, and a storage medium, which relate to an image processing field, in particular to fields of a three-dimensional display technology and a computer graphics technology, and are applied to augmented reality, virtual reality, mixed reality or other scenarios. The method includes: obtaining an adjusted parameter value in response to a triggering operation of an editing control for a parameter item to be adjusted; generating a three-dimensional avatar related to a target image, based on the adjusted parameter value, three-dimensional model data, and target image data of the target image; generating a preview image of the three-dimensional avatar according to the three-dimensional avatar; and displaying the three-dimensional avatar by using the adjusted parameter value, in response to a determination that a preview effect of the preview image meets an expected effect.
