In this paper we present a study of ZnS thin films thermally deposited on
glass substrates, with different optical thicknesses. On topography micrographs
and feature parameters obtained by Atomic Force Microscope, we pursued the
islands formation
and growing in ZnS thin films even on the same optical
thickness of the film. For doing so, we analyzed the micrographs surface, using
Watershed Segmentation and Wolf pruning that allow the detection of
significant features on surfaces, Grain sorting operator and Parameter
Distribution Study.
