1. A method for processing a radiographic image of a scanned object, the method comprising: acquiring radiographic image data corresponding to a scanned object; identifying one or more regions of interest in the radiographic image data corresponding to the scanned object by filtering the radiographic image data corresponding to the scanned object through an image-processing filter to identify the one or more regions of interest; generating a noise-filtered radiographic image corresponding to the scanned object, based on the filtered radiographic image data by classifying one or more image pixels comprising the filtered radiographic image data based on a variance level associated with one or more of the image pixels; and performing an image-contrast comparison of the radiographic image data corresponding to the scanned object and one or more reference radiographic images, to identify one or more defects in the radiographic image data corresponding to the scanned object.
