Boxplot showing the median and interquartile range of Dice index (relative to the expert ground truth), reflecting the accuracy of crowd worker demarcations of the 410 test images. A, Performance of different consensus-level segmentations, both with (red) and without (blue) incorporation of input from the most accurate user (user 16). B, Performance of individual users as well as the 4-consensus (median Dice 0.7551 including user sixteen; 0.7167 excluding user sixteen). The most accurate user (user sixteen) had a median Dice index of 0.7216 with the expert ground truth
