getSorensenDiceCoefficient

Determines the overlap of two binary images using the Sorensen-Dice coefficent.

A value of 0 suggests no overlap, 1 means perfect overlap. The Sorensen-Dice coefficient is saved in the colum ‘Sorensen_Dice_coefficient’. Note that the Sorensen-Dice coefficient s can be calculated from the Jaccard index j using this formula:

s = f(j) = 2 j / (j + 1)
