Title:
IMAGE GENERATION METHOD AND APPARATUS, AND COMPUTER
Document Type and Number:
WIPO Patent Application WO/2021/052103
Kind Code:
A1
Abstract:
Disclosed is an image generation method, etc., for generating high-quality images. The method comprises: obtaining a target vector; inputting the target vector into a first generator and a second generator separately to correspondingly generate a first sub-image and a second sub-image, the first generator being obtained by a server training, according to low-frequency images and a first random noise variable satisfying the normal distribution, an initially configured first generative adversarial network (GAN), the second generator being obtained by the server training, according to high-frequency images and a second random noise variable satisfying the normal distribution, an initially configured second GAN, and the frequency of the low-frequency images being lower than the frequency of the high-frequency images; and synthesize the first sub-image and the second sub-image to obtain a target image.
