How to not Suffer Losses When Buy Mens cufflinks?

Common edge detection algorithm is based on the various operators. The system uses Sobel operator pearl cufflinks gray image is converted into a gradient map to get the information of the edge of the pearl cufflinks. Subsequent operations are based on the pearl cufflinks gradient map. pearl cufflinks positioning due to the shooting of the environment in order to constraint the position of the free fall of pearl cufflinks, 17 Zhejiang University, a master's degree thesis in Chapter 2 System structure of a glass tube in the center of the lighting inside the sphere, the The tube increases the difficulty of positioning of pearl cufflinks. As shown in Figure 2.9, each of the two white areas in the left and right sides of the picture, this is the glass tube. Pearl cufflinks fall into the location of the area photographed is not fixed, it is possible to overlap with the glass tube, this positioning according to the pearl cufflinks became certain difficulties.

Figure 2.9 pearl cufflinks sample diagram of the system positioning steps: Gradient of pearl cufflinks binarization, the binarization is mysterious in addition to noise, Okazaki this global maximum between variance method for binarization. To the end of the year again, whether wedding or birthdays, or gifts, cufflinks, people rush to buy gold or gems jewelry that has become a popular product.  Calculate the level of brightness histogram. ? Analysis of the histogram to find the boundary around the pearl cufflinks. Can know by observation of pearl cufflinks picture, both sides of the glass with vertical, then the corresponding position of the histogram value is relatively large, pearl cufflinks, whether overlapping or not with the boundary, the left and right at the boundary of the histogram size a critical value, the boundary can be found through this feature.
 Computing around the vertical direction within the boundary limit the scope of direct force 'diagram. Analysis of the histogram, the same can be found in the histogram thresholds, Gen H is the upper and lower bounds of pearl cufflinks.
