Automatic Segmentation of Dermoscopic Images by Iterative Classification

Table 3

Average accuracy of segmentation, quantified by the percentage of contour with an error ≤0.5 mm, showing the performance of the proposed ICS method against alternative solutions. Borders manually drawn by three dermatologists, and their agreement, are considered as the ground-truth reference for accuracy assessment.
