Effect of surface-partial-volume correction and adaptive threshold on segmentation of uroliths in computed tomography
Fig 3
Correlation plots of estimated vs. reference standard diameters (A, B, E, F, I, J, M, N) and volumes (C, D, G, H, K, L, O, P) for all four segmentation approaches (A-D, E-H, I-L, M-P).
The plots were created with all 101 uroliths using the optimal average parameters from the repeated optimization and validation procedure (see Table 1). Obviously, all approaches yield similar results, with good correlations.
