• Abstract summary: Adapting a segmentation model from a labeled source domain to a target domain is one of the most challenging problems in domain adaptation. We leverage text-to-image diffusion models to generate a synthetic target dataset with photo-realistic images. Experiments show that our method surpasses the state-of-the-art OSUDA methods by up to +7.1%.

• Abstract: Adapting a segmentation model from a labeled source domain to a target domain, where a single unlabeled datum is available, is one the most challenging problems in domain adaptation and is otherwise known as one-shot unsupervised domain adaptation (OSUDA). Most of the prior works have addressed the problem by relying on style transfer techniques, where the source images are stylized to have the appearance of the target domain. Departing from the common notion of transferring only the target ``texture'' information, we leverage text-to-image diffusion models (e.g., Stable Diffusion) to generate a synthetic target dataset with photo-realistic images that not only faithfully depict the style of the target domain, but are also characterized by novel scenes in diverse contexts. The text interface in our method Data AugmenTation with diffUsion Models (DATUM) endows us with the possibility of guiding the generation of images towards desired semantic concepts while respecting the original spatial context of a single training image, which is not possible in existing OSUDA methods. Extensive experiments on standard benchmarks show that our DATUM surpasses the state-of-the-art OSUDA methods by up to +7.1%. The implementation is available at https://github.com/yasserben/DATUM

  Single-domain generalized object detection aims to enhance a model's generalizability to multiple unseen target domains. This is a practical yet challenging task as it requires the model to address domain shift without incorporating target domain data into training. We propose a novel phrase grounding-based style transfer approach for the task.

We propose a novel method for Few-Shot Unsupervised Domain Adaptation (FSUDA), where only a limited number of unlabeled target domain samples are available for training.

  zero-shot GAN adaptation aims to reuse well-trained generators to synthesize images of an unseen target domain. With only a single representative text feature instead of real images, the synthesized images gradually lose diversity. We propose a novel method to find semantic variations of the target text in the CLIP space.

  Domain adaptation typically requires to access source domain data to utilize their distribution information for domain alignment with the target data. In many real-world scenarios, the source data may not be accessible during the model adaptation in the target domain due to privacy issue. We present a novel denoised pseudo-labeling method for this problem, which effectively makes use of the source model and unlabeled target data.

  This paper studies how much it can help address domain shifts if we further have a few target samples labeled. To explore the full potential of landmarks, we incorporate a prototypical alignment (PA) module which calculates a target prototype for each class from the landmarks. Specifically, we severely perturb the labeled images, making PA non-trivial to achieve and thus promoting model generalizability.
