Unsupervised Image Transformation Learning via Generative Adversarial Networks
share
In this work, we study the image transformation problem by learning the underlying transformations from a collection of images using Generative Adversarial Networks (GANs). Specifically, we propose an unsupervised learning framework, termed as TrGAN, to project images onto a transformation space that is shared by the generator and the discriminator. Any two points in this projected space define a transformation that can guide the image generation process, leading to continuous semantic change. By projecting a pair of images onto the transformation space, we are able to adequately extract the semantic variation between them and further apply the extracted semantic to facilitating image editing, including not only transferring image styles (e.g., changing day to night) but also manipulating image contents (e.g., adding clouds in the sky). Code and models are available at https://genforce.github.io/trgan.
