Balanced Unsupervised Style Transfer using Generative Adversarial Networks


Generative adversarial networks (GAN) have recently shown major progress in generating images, as in cross-model generation or applying a specific style to images. We utilize this progress in order to improve generation of simulated images required for computer vision tasks. Our objective function is based on principles acquired from recently published work: preserving key attributes between the input and the translated image; balancing the power of the discriminator against the generator in order to better achieve Nash equilibrium; and using a task-dedicated loss in order to ensure that the generated images are valuable for the desired task at hand.
