Classification: CPC G | IPC G

Claim 9:
10. A method performed by a computer, the method comprising:
receiving color data for input pixels of an input image and an input set of features used to render the input image of a three-dimensional animation environment, and a reference image, wherein the input pixels are of a first resolution;
configuring a generative adversarial network comprising:
a generator comprising a first neural network having a first set of parameters, the generator configured to generate, using the color data and the input set of features, an output image having a second resolution that is different from the first resolution; and
a discriminator coupled to the generator, the discriminator comprising a second neural network having a second set of parameters, the discriminator configured to:
receive the reference image, and the output image generated by the generator;
generate a quality metric based on a comparison of the output image with the reference image; and
output the quality metric to the generator, wherein the generator is further configured to update the first set of parameters based on the quality metric and to produce an updated output image using the updated first set of parameters; and

training the generative adversarial network to obtain an optimized first set of parameters and an optimized second set of parameters that reduce the quality metric generated by the discriminator.
