Abstract
Articles such as glass jars filled with food products are inspected for defects by scanning an x-ray image to provide video signals which are processed in a novel manner to provide increased sensitivity to detect very small foreign particles without decreasing a tolerance for normal variations, to inspect substantially the entire contents of a container such as a jar even if it has a varying diameter, without the need for precise positioning of the articles within an inspection zone, and without a need for an x-ray or optical mask tailored to fit each type of jar to be inspected.
