The difficulty stems above all from the pearl cufflinks image acquisition

No time, micro-flaw, small flaws, defects, heavy flaw of the automatic sorting. Flat, and other shapes. Pearl cufflinks in need of sorting. Able to achieve the shape of pearl cufflinks evaluation criteria as follows: round, oval, automatic sorting luster strong, strong, medium, or weak; gloss irregular distribution of the automatic election of a different color pearl cufflinks. Make appropriate adjustments towards the cufflinks China's pearl cufflinks industry there is still much room for improvement, the introduction of pearl cufflinks quality inspection system, the automation of the production of pearl cufflinks, intelligent, and will be able to exclude most of the drawbacks of the artificial separation. Cufflinks in the minds of consumers
Color evaluation criteria: a series of white, red, yellow, black; the same color, the color of pearl cufflinks automatic sorting according to the color differences. Demonstration sector shown in Figure 1.4. You can see, the shape, texture classification relatively small number of applications on the market is not widely used. In addition Bin moments shape classification method of pearl cufflinks. ZhaoShu'an, Zhou Hong, LiuJing, He Li, GE Li, etc. who also made fruit detection method based on the the Zernike Dongjian. People the Guan Guangrongt proposed fuzzy classification based on Zernike moment people meters. Journal of Zhejiang University Chapter 1 Introduction Figure I. When we arrived home, I began to put the cufflinks in order.
 An intellectual image analysis system abroad, has long been a similar study. For example, M-Recce, J. Taylor, who proposed the classification based on the visual quality of orange, "the DM Bulanon et  in 2001 to research and development of apple-picking machine hand machine T. Control visual navigation system, Paul of H. Heinemann,, Niranjan of P. Pathare and Morrowl6, Charles] proposed a machine vision-based automated potato grading, automatic detection based on machine vision system. Suddenly I found the mens cufflinks were missing. Technical difficulties pearl cufflinks facing some technical difficulties of automatic sorting.
The difficulty stems above all from the pearl cufflinks image acquisition. In order to minimize the follow-up testing. T for the difficulty, demanding access to images of pearl cufflinks. Ordinary digital camera pictures of pearl cuff links, and often lack of clarity can not be restored to the real texture of pearl cufflinks, and the day.
