Classification: CPC G  A | IPC A  G

Claim 0:
1. A learning method of a generative model that estimates, from a first image including low resolution information having a relatively low resolution, a second image including high resolution information having a relatively high resolution, the method comprising:
a first image generation step of generating the first image from a second image for learning;
a generator input step of inputting only the first image to a generator of a generative adversarial network including the generator which is a generative model that generates a virtual second image by using the first image and a discriminator that identifies the second image for learning and the virtual second image;
a first discriminator input step of inputting the second image for learning and meta information of the second image for learning to the discriminator, wherein the meta information comprises part information of the second image for learning, and wherein the part information of the second image comprises a plurality of different parts of an object; and
a second discriminator input step of inputting the virtual second image and meta information of the virtual second image to the discriminator, wherein the meta information of the virtual second image is the same as the meta information of the second image; and
a learning step of using the first image and the meta information to identify whether an input high resolution image is the second image or the virtual second image.
