ABSTRACT 

In this paper, we have prepared CdS thin films by chemical spray method on the substrates in (200C°) and then we annealed the samples of thin film by oven heat in the temperature (250-400C°) and we took images of the thin film membranes before and after annealing by a scanning electron microscope (SEM) in magnification (1000X). The acquisition image converted to binary image of multithresholdand then applied image processing where used seed filling algorithm to analysis images and study the porosity on the surfaces of thin films and that the annealing under different temperature works to reduce the ratioand number of pores on the surface of the thin membrane.
