Physical properties measurement on nanofiber images

This paper deals with an automatic measurement of nanofiber properties on digital images. Nanofibers are manufactured by electrospinning method with diameters in the range of one or two orders magnitude smaller than conventional textile fibers. Individual algorithms and functions suitably use instruments of computer image processing. A first parameter filling is defined by a ratio of a fiber area and a whole area. Next two parameters are a fiber radius and a hole size. Measured values are converted to the real-world units by using an included scale. Obtained information can be used for determining property as e.g. filtration ability of inspected nanofiber material.
