(a) Depiction of the investigated dimensions of a detaching droplet (silicone oil sample). Steps of the original imagine processing; detail of the neck diameter \({d\left(x\right)=d}_{min}\): (b) negative imagine, (c) distribution of gray levels on the inspection line, corresponding to the minimum thickness of the filament, (d) final binarized image. Numerical interface (e); the mesh/cell size is 27.5 μm and the VF \(\in \left[0.1, 0.9\right]\) covers 3 cells. The median line VF = 0.5 approximates the computed interface with a maximum error of 42 μm.
