Fig. 3From: Automated prediction of early spontaneous miscarriage based on the analyzing ultrasonographic gestational sac imaging by the convolutional neural network: a case-control and cohort studyIllustration of the quantitative accuracy assessment of gestational sac region segmentation. The yellow ellipse is an area (G) manually labeled by a doctor before the test, while the green ellipse indicates the segmentation area (S) predicted by the algorithm. The intersection area between S and G is the true positive predicted area (TP). FP (false positive predicted area) = S-TP; FN (false negative predicted area) = G-TPBack to article page
