Constrained-CNN Losses for Weakly Supervised Segmentation
In the recent years, deep convolutional neural networks (CNNs) have been dominating semantic segmentation problems, both in computer vision and medical imaging, achieving ground-breaking performances when full-supervision is available (Long et al., 2015; Dolz et al., 2018; Litjens et al., 2017). In semantic segmentation, full supervision requires laborious pixel/voxel annotations, which may not be available in a breadth of applications, more so when dealing with volumetric data. Furthermore, pixel/voxel level annotations become a seri ous impediment for scaling deep segmentation networks to new object categories or target domains.
