more components are present and/or properly positioned in the composite article
by use of infrared radiation. Also disclosed is a process and system for defining
a window in an image of the article, scanning the defined window to determine a
position of the edge and redefining the window in the event that the edge is not
located within the defined window during scanning of the defined window.
