2021 Machine Learning and Knowledge Extraction  
Here, we suggest using minimal user interaction in the form of extreme point clicks to train a segmentation model which, in effect, can be used to speed up medical image annotation.  ...  This initial segmentation is then used as a noisy supervision signal to train a fully convolutional network that can segment the organ of interest, based on the provided user clicks.  ...  Previous work primarily used boundary box annotations for weakly supervised learning in 2D/3D medical imaging, such as Rajchl et al.
