Segmentation parameter optimization for the calibrated phantom image (Hausdorff criterion). (a) Best segmentation result for threshold value of T res = 5, b) Best segmentation result for T res = 20, (c) Best segmentation result for T res = 50, (d) Hausdorff distance surface as a function of ε and β =β 1 = β 2 for 3 different thresholds: T res = 5 with minimum error value of 2.25 (ε = 0.1, β = 12.92), T res = 20with minimum error value of 0.38 (ε = 4.64, β = 600), T res = 50 with minimum error value of 0.09 (ε = 0.1, β = 0.6).
