Abstract
Systems, methods, and computer-readable media for automated characterization of fillers and pores in media using energy-dispersive X-ray spectroscopy (EDS) are disclosed. An EDS system comprising a scanning electron microscope and an EDS detector may be used to obtain an EDS image of media, such as a polymer component. The EDS image may be binarized and segmented to separate the fillers from the pores in the polymer component. Contours may be drawn around the filler segments, and these contours may be analyzed to determine geometrical properties of the fillers, such as the centroids and the area. The results may be plotted in histograms and displayed to a user. The results may also be used to determine whether the polymer component is within material specification and, if not, process parameters may be adjusted. Machine learning models for classifying the EDS images are also disclosed.
