Digital Image Processing is an increasing expansion area in some field of application that uses the interpretation of images as tool. Quantitative Metallography area applied to Materials Sciences uses this technique for characterization of phase volumetric fractions, grain size, inclusion distribution determination and other parameters that influence the properties of the materials. The present paper has, as main objective, to present and validate the software Segmentation by Artificial Neural Network (SVRNA), developed by the authors. This software, based on artificial neural network, makes the percentile constituent counting in time reduced in relation to the conventional model. The study is carried out over ABNT 1020 and 1045 steel and nodular cast iron samples. Statistical analysis showed that this software is efficient for admitted degree of significance. It has concluded, therefore, that the program can be used in applications in the field of Material Sciences for determination of microstructures.
