Automatic spent fuel ID-number reader (II) image-processing technique

This paper reports on an image-processing technique for automatic spent fuel ID-number reader system. As a result, efficiency and reliability of the reader system is improved. To obtain reliable ID-number identification-capability, there are many items to be considered. Some of the important ones are appropriate lighting, high speed processors and suitable algorithm. After developing the technique on the items, the applicability of the image-processing technique for the reader system is verified. ID-numbers are accurately identified, and the time required for one ID-number reading is obtained in about 2 seconds. The result is one tenth of the conventional visual identification
