At Sony's Compact Disc (hereafter called CD) factory, inspection of the CD label is done by human visual inspectors. But now, in order to automate that inspection, a system for the detection and prevention of errors has been developed and installed in line with the label printing machine. One of the features of this system is that 100% in-line inspection is possible by processing four images for each CD in about 0.8 seconds. For this a high speed algolithm which matches the test image to a mastered image stored in computer memory was developed.
