Digital image processing techniques have been widely used for studying morphological properties of many diferent images, such as medical, satellite and materials images. In this work the study of morphological properties of niobium nitride (NbN), tantalum nitride (TaN), zirconium nitride (ZrN) and chromium nitride (CrN), employing the scanning probe microscopy (SPM) in the atomic force microscopy method (AFM) is present. These images were annalysed employing image processing techniques. To determine the roughness, fractal dimension (FD) was used. Fractal dimension is a tool that allows to calculate the surface complexity. The number and grains size was determined by using the Hessian method.
