Topology cuts: A novel min-cut/max-flow algorithm for topology preserving segmentation in N-D images
13 years 7 months ago
Topology is an important prior in many image segmentation tasks. In this paper, we design and implement a novel graph-based min-cut/max-flow algorithm that incorporates topology p...
