Abstract: A method for generating a virtual character is provided, relating to a field of artificial intelligence technology, and in particular, to fields of computer vision, virtual/augmented reality and meta universe technologies. The implementation includes: converting a plurality of points of an initial three-dimensional virtual character into a frequency domain, so as to obtain a plurality of frequency domain points; rendering the plurality of frequency domain points, so as to generate a first three-dimensional virtual character; determining a perceptual feature of the first three-dimensional virtual character; and generating a second three-dimensional virtual character according to a difference between the perceptual feature and a predetermined style feature. An electronic device and a storage medium are also provided.

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.
