Table 2.
Intraclass correlation coefficient values for computed Velocity-Informatics variables using different workflows. This analysis includes CFD simulation results from all 18 cases. 1 to 4 indicate Protocols 1–4. Additionally, Wilcoxon Rank Sum Tests were conducted to compute the p-value between computed variables following Protocol 2 and Protocol 3. RLN RunLengthNonuniformity, GLN GrayLevelNonUniformity, LRHGLE LongRunHighGrayLevelEmphasis, LAHGLE LargeAreaHighGrayLevelEmphasis, STD standard deviation.
