Analysis and Algorithmic Generation of Hepatic Vascular Systems

Table 3

For different geometric features, the table lists the one-population similarity within the human clinical PV, HV, and corrosion cast PV data sets. Moreover, the two-population similarity between the clinical and corrosion cast PV as well as the clinical PV and HV data sets is listed. Unlike for the individual features, the numerical values of the averages in the one- and two-population cases cannot be compared due to the different averaging formulas (7) and (8).
