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]. It requires neither user input nor supervised learning phase and assumes an unknown number of segments. 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. : Fine-tuning convolutional neural networks for biomedical image analysis: actively and incrementally.
