NEURAL NETWORK-BASED IMAGE-TO-IMAGE TRANSLATION

Abstract:

A system and method for neural-network based image-to-image translation is provided. The system includes a generator network which receives an image and generates a first synthetic image based on the received image. The first synthetic image is different from the image in appearance, style, or domain. The system includes a feature-to-image generator that extracts a feature map from an intermediate layer of the generator network and generates a second synthetic image. The system further includes a first discriminator network that generates a result indicative of whether the first synthetic image is real or fake in comparison to a first reference image and a second discriminator network that generates a result indicative of whether the second synthetic image is real or fake in comparison to a second reference image. The system further includes a processor which trains the first generator network in adversarial manner based on losses associated with the results.
