## Dataset description
SLIVER07 is a benchmark challenge to evaluate liver segmentation methods on contrast-enhanced CT scans during the central venous phase. It originated from the MICCAI 2007 Grand Challenge, where 16 teams (10 automatic, 6 interactive) evaluated their methods on a shared dataset. Algorithms included statistical shape models, atlas registration, level-sets, graph-cuts, and rule-based systems.
