Histogram of the Dice coefficients (${\displaystyle {\mathrm{D}\mathrm{C}}_{\rho }}$). The three coloured bars represent the percentage of cases where the agreement between pairs of markings was considered poor, moderate, good, and excellent. DC, Dice coefficient; ${\displaystyle {\mathrm{G}\mathrm{T}}_{\mathrm{D}\mathrm{P}}}$, ground truth marking for the DP; ${\displaystyle {\mathrm{G}\mathrm{T}}_{\mathrm{Q}\mathrm{L}\mathrm{F}}}$, ground truth marking for the QLF; ${\displaystyle {\mathrm{M}}_{\mathrm{Q}\mathrm{L}\mathrm{F}}}$, marking from the QLF-software; GT, ground truth; DP, digital photographs; QLF, quantitative light-induced fluorescence.
