dc.descriptionNanoporous anodized alumina oxide have been used as templates for obtaining nanomaterials such as nanowires, which exhibit interesting electronic, magnetic and optical properties. This article presents how the regularity of the spatial distribution of pores in such templates, which affects several of the physical properties of the obtained nanomaterials, has been objectively quantified. The method uses adaptive thresholding, wave propagation image analysis methods, as well as an hexagonality measurement which was found to be particularly suitable because of its locality and invariance to translation, rotation and scaling. A comparison between commercial and laboratory-made samples is presented in order to test the method, resulting higher hexagonality for the latter type of templates.
