(eds.) : Semi-supervised 3D abdominal multi-organ segmentation via deep multi-planar co-training. In this article we explained the basics of modern image segmentation, which is powered by deep learning architectures like CNN and FCNN. We further propose two constrains as regularization schemes for the training procedure to drive the model towards optimal segmentation by avoiding some unreasonable results. In this paper, we revisit the problem of purely unsupervised image segmentation and propose a novel deep architecture for this problem. • LNCS, vol. 2672–2680 (2014), Tran, D., Ranganath, R., Blei, D.M.

This chapter presents unsupervised domain adaptation methods using adversarial learning, to generalize the ConvNets for medical image segmentation tasks. Also, features on superpixels are much more robust than features on pixels only. Specifically, we design the generator with a CNN producing the segmentation results and a decoder redrawing the CT volume based on the segmentation results. To the best of our knowledge, it is the first attempt to unite keypoint- Citation: Fan S, Bian Y, Chen H, Kang Y, Yang Q and Tan T (2020) Unsupervised Cerebrovascular Segmentation of TOF-MRA Images Based on Deep Neural Network and Hidden Markov Random Field Model.

LNCS, vol. 1–8 (2020), Cubuk, E., Zoph, B., Mane, D., et al. In this paper, we present an unsupervised segmentation method that combines graph-based clustering and high-level semantic features. aims at revisiting the unsupervised image segmentation problem with new tools and new ideas from the recent history and success of deep learning [55] and from the recent results of supervised semantic segmentation [5, 20, 58]. 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.

However, vessels can look vastly different, depending on the transient imaging conditions, and collecting data for supervised training is laborious.
