Abstract

An image processing method for recognizing a material contained in an article includes the following steps: transilluminating the article with X-rays; generating, by an X-ray detector, signals representing the X-rays passing through the article; applying the signals to a computer system as continuous image data; subdividing the image data into defined zone-wise image strips; briefly storing the image strips in an image data memory; and determining the material from the image strips before a completion of the transilluminating step.
