"Detailed knowledge of material structure is necessary in advanced applications. Commercial systems use systematic scanning of small patches of structure cuts. For the composition of the cut a commercial SW must be used.Since an exact geometric and photometric relation of the scanned images is not known, composition of the overall image is non-trivial. Two independent methods exploiting image overlaps for precise registration are proposed and evaluated.The first method is based on robust matching of maximally stable extreme regions, the second one compares image columns. Both methods applied to textile composite show comparable performance and the elapsed time is very low in both cases.The paper presents details of applied methods, immediate and final results predominantly in graphical form." .
