| Popis: | The binarization of transmission electron micrographs of thin granular films is an essential step for the statistical study of the film morphology in the framework of scaling laws and fractal theory. An image processing is developed, leading to an unambiguous optimum binarization threshold, without any loss of information. This treatment, efficient even on films with unimodal gray level histograms, is tested on different granular metallic or metal-dielectric films La binarisation des cliches de microscopie electronique par transmission de couches minces granulaires est une etape indispensable pour l'etude statistique de la morphologie de la couche, dans le cadre des lois d'echelle et de la theorie fractale. Nous presentons un processus de traitement d'image conduisant a un seuil optimal de binarisation, sans perte d'information. Ce traitement, efficace meme sur des films presentant un histogramme de niveaux de gris unimodal, est teste sur differentes couches minces granulaires de metal ou de composes metal-dielectrique |
