• Abstract summary: It is desirable that users should annotate unseen data and have an automated system to unobtrusively rate their performance. We evaluate two methods the generation of synthetic individual cell images: conditional Generative Adversarial Networks and Diffusion Models. Users could not detect 52.12% of generated images by proofing the feasibility to replace the original cells with synthetic cells without being noticed.

• Abstract: Image annotation is one essential prior step to enable data-driven algorithms. In medical imaging, having large and reliably annotated data sets is crucial to recognize various diseases robustly. However, annotator performance varies immensely, thus impacts model training. Therefore, often multiple annotators should be employed, which is however expensive and resource-intensive. Hence, it is desirable that users should annotate unseen data and have an automated system to unobtrusively rate their performance during this process. We examine such a system based on whole slide images (WSIs) showing lung fluid cells. We evaluate two methods the generation of synthetic individual cell images: conditional Generative Adversarial Networks and Diffusion Models (DM). For qualitative and quantitative evaluation, we conduct a user study to highlight the suitability of generated cells. Users could not detect 52.12% of generated images by DM proofing the feasibility to replace the original cells with synthetic cells without being noticed.

  Deep learning models can learn to detect breast cancer from mammograms. However, challenges with overfitting and poor generalisability prevent their routine use in the clinic. Data augmentation techniques can be used to improve generalisability.

• Trustworthy image-to-image translation: evaluating uncertainty calibration in unpaired training scenarios [0.0]
  Mammographic screening is an effective method for detecting breast cancer, facilitating early diagnosis. Deep neural networks have been shown effective in some studies, but their tendency to overfit leaves considerable risk for poor generalisation and misdiagnosis. Data augmentation schemes based on unpaired neural style transfer models have been proposed that improve generalisability. We evaluate their performance when trained on image patches parsed from three open access mammography datasets and one non-medical image dataset.

  We propose DiffDoctor, a two-stage pipeline to assist image diffusion models in generating fewer artifacts. We collect a dataset of over 1M flawed synthesized images and set up an efficient human-in-the-loop annotation process. The learned artifact detector is then involved in the second stage to tune the diffusion model through assigning a per-pixel confidence map for each image.
