WebDice Similarity Coefficient. Closely related to the classification accuracy measures previously described, the Dice similarity coefficient, often abbreviated as just Dice or DSC, is a measure of overlap of two structures. It was first proposed as a measure looking at species overlap in ecological studies and is named after the author [8].
