Abstract

Image processing techniques are recently employed in chemical engineering problems to evaluate and quantify result of experiments. Some of the most applications of IMAGE PROCESSING are the fabrication process of nanowires, membranes and catalysts. A new method to identify domains and quantify ordering degree of SEM micrographs of anodic porous alumina is presented in this paper. This method begins by take SEM micrographs from pores and identifying their centers, then their neighbors are detected and hexagons are identified. Then based on the configuration of neighboring pores an angel is assigned to the central pore of the hexagon. A spreading algorithm is proposed based on concatenating neighboring pores so that the standard deviations of angels of the whole domain do not exceed a specific threshold. Domain sizes are used as quantification criteria for anodic oxide aluminum ordering. Using the proposed technique proper anodization time to develop optimum domains in different anodization conditions could be achieved. Our algorithm greatly excels previous approaches identifying domain borders.
