Jaccard similarity coefficient. (left) in blue the ground truth segmentation of a mitochondrion, in red the result obtained with an automated segmentation algorithm; TP is the intersection of red and blue regions, i.e. the correctly segmented piece of mitochondrion; FN is the only blue area, i.e. the part of mitochondrion segmented as background; FP is the only red area, i.e. the background segmented as mitocondrion; TN is the rest of the image, i.e. the correctly segmented background; (right) representation of the Jaccard coefficient as the relation between the purple and green areas
