Wilcoxon Signed Ranks Test for the mean-IoU data in Table 1. The graph obtained from the Wilcoxon Signed Ranks test using the Statistics and Machine Learning Toolbox of Matlab2018b. Statistical toolbox indicated a higher positive range value than the negative range value. The p value of this test was 1.998E−18 less than the significance value. We can thus conclude that a statistically significant difference appeared between both methods, and the proposed method (New_skel) achieved major improvement compared to the classic method (classical_skel).
