• Authors: Rajiv Kumar, Rishabh Dabral, G. Sivakumar
• Abstract summary: Unsupervised image-to-image translation is used to transform images from a source domain to generate images in a target domain without using source-target image pairs. We propose a new method that uses a single shared discriminator between the two GANs, which improves the overall efficacy. Our results indicate that even without adding attention mechanisms, our method performs at par with attention-based methods and generates images of comparable quality.

• Abstract: Unsupervised image-to-image translation is used to transform images from a source domain to generate images in a target domain without using source-target image pairs. Promising results have been obtained for this problem in an adversarial setting using two independent GANs and attention mechanisms. We propose a new method that uses a single shared discriminator between the two GANs, which improves the overall efficacy. We assess the qualitative and quantitative results on image transfiguration, a cross-domain translation task, in a setting where the target domain shares similar semantics to the source domain. Our results indicate that even without adding attention mechanisms, our method performs at par with attention-based methods and generates images of comparable quality.

  We propose a domain-agnostic i2i method for fine-grained problems, where the domains are related. We present a novel approach that relies on training the generative model to produce images that both share distinctive information of the associated source image. We validate our method on the CelebA-HQ and AFHQ datasets by demonstrating improvements in terms of visual quality.

  We propose a new unsupervised domain adaptation method for the semantic segmentation of very high resolution images.

One of the most common strategies is to translate images from the source domain to the target domain and then align their marginal distributions in the feature space using adversarial learning. Here, we present an innovative framework, designed to mitigate the image translation bias and align cross-domain features with the same category.
