Preserving instance continuity and length in segmentation through connectivity-aware loss computation
Karol Szustakowski, Luk Frank, Julia Esser +2
In many biomedical segmentation tasks, the preservation of elongated structure continuity and length is more important than voxel-wise accuracy. We propose two novel loss functions…
