As in the case of supervised image segmentation, the proposed CNN assigns labels to pixels that denote the cluster to which the pixel belongs. Papers With Code is a free resource with all data licensed under CC-BY-SA. 9901, pp. Many recent segmentation methods use superpixels because they reduce the size of the segmentation problem by order of magnitude. Introduction. Deep Learning methods have achieved great success in computer vision. Also, features on superpixels are much more robust than features on pixels only. 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. This is true for large-scale im-age classification and even more for segmentation (pixel-wise classification) where the annotation cost per image is very high [38, 21]. 20 Jun 2020 Eng. Our experiments show the potential abilities of unsupervised deep representation learning for medical image segmentation. Furthermore, it is extremely difficult to segment an image into an arbitrary number (≥ 2) of plausible regions. The task of blood vessel segmentation in microscopy images is crucial for many diagnostic and research applications. : MICCAI multi-atlas labeling beyond the cranial vault-workshop and challenge (2015).

Imaging, Sun, R., Zhu, X., Wu, C., et al. : Fine-tuning convolutional neural networks for biomedical image analysis: actively and incrementally. Since you ask for image segmentation and not semantic / instance segmentation, I presume you don't require the labelling for each segment in the image. It requires neither user input nor supervised learning phase and assumes an unknown number of segments. Image Anal. (2015), Landman, B., Xu, Z., Eugenio, I., et al. 9351, pp. 4360–4369 (2019). We further propose two constrains as regularization schemes for the training procedure to drive the model towards optimal segmentation by avoiding some unreasonable results.

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.
