We propose a novel adversarial learning framework for unsupervised training of CNNs in CT image segmentation. IEEE Trans. Abstract. Image segmentation is widely used as an initial phase of many image processing tasks in computer vision and image analysis. As in the case of supervised image segmentation, the proposed CNN assigns labels to pixels that denote the cluster to which the pixel belongs. 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. 234–241.
