Furthermore, it is extremely difficult to segment an image into an arbitrary number (≥ 2) of plausible regions. This chapter presents unsupervised domain adaptation methods using adversarial learning, to generalize the ConvNets for medical image segmentation tasks. Spherical k -means training is much faster … Unlabeled data, on … In the unsupervised scenario, however, no training images or ground truth labels of pixels are given beforehand. Due to lack of corresponding images, the unsupervised image translation is considered more challenging, but it is more applicable since collecting training data is easier which is quite meaningful in the context of domain adaptation for segmentation. Shicai Yang Historically, this problem has been studied in the unsupervised setting as a clustering problem: given an image, produce a pixelwise prediction that segments the image into coherent clusters corresponding to objects in the image. Our main contribution is to combine unsupervised representation learning with conventional clustering for pathology image segmentation. Imaging, Roth, H., Farag, A., Turkbey, E., et al. Papers With Code is a free resource with all data licensed under CC-BY-SA. Although having achieved great success in medical image segmentation, deep learning-based approaches usually require large amounts of well-annotated data, which can be extremely expensive in the field of medical image analysis.
