We propose to use a neural network approach in conjunction with digital holographic microscopy in order
to rapidly determine relevant parameters such as the core and shell diameter of coated, non-absorbing
spheres. We do so without requiring a time-consuming reconstruction of the cell image. In contrast to
previous approaches, we are able to obtain a continuous value for parameters such as size, as opposed
to binning into a discrete number of categories. Also, we are able to separately determine both core and
shell diameter. For simulated particle sizes ranging between 7 mm and 20 mm we obtain accuracies of
(4.4 +- 0.2)% and (0.74 +- 0.01)% for the core and shell diameter, respectively.
