Scale-Space Autoencoders for Unsupervised Anomaly Segmentation in Brain MRI

1 code implementation23 Jun 2020 Christoph Baur, Benedikt Wiestler, Shadi Albarqouni, Nassir Navab

Brain pathologies can vary greatly in size and shape, ranging from few pixels (i. e. MS lesions) to large, space-occupying tumors.

Autoencoders for Unsupervised Anomaly Segmentation in Brain MR Images: A Comparative Study

1 code implementation7 Apr 2020 Christoph Baur, Stefan Denner, Benedikt Wiestler, Shadi Albarqouni, Nassir Navab

Deep unsupervised representation learning has recently led to new approaches in the field of Unsupervised Anomaly Detection (UAD) in brain MRI.

Generating Highly Realistic Images of Skin Lesions with GANs

no code implementations5 Sep 2018 Christoph Baur, Shadi Albarqouni, Nassir Navab

As many other machine learning driven medical image analysis tasks, skin image analysis suffers from a chronic lack of labeled data and skewed class distributions, which poses problems for the training of robust and well-generalizing models.
