The mens cufflinks are not exception

 The mens cufflinks are not exception. Shape detection shape detection module is responsible for pearl cufflinks shape recognition. The shape of the pearl cufflinks ever-changing system structure in accordance with Chapter 2 of the Zhejiang University Journal of rough division can mainly be divided into round, oval, flat, other shapes. In accordance with the finer points method can be divided into a perfect circle, round, nearly round, oblong, short oval, surrounded by light, the two faces of light, arrow head, flat head, the other shape.
Although the shape of the pearl cufflinks, but is mainly based on round-based. The shape of the detection module according to the above criteria to determine the shape of the pearl cufflinks. Common shape descriptors, Fourier descriptors child grieved, wavelet descriptors, shape descriptors. However, the calculation of these descriptors is time-consuming and not suitable for real-time detection. The shape detection using randomized Hough transform. Hough transform is one of the methods to identify the geometry of image processing from image, which is widely used, there are many improved algorithm. Recently, a jewelry brands are disclosed that a type of 18K gold mens cufflinks did not reach the standard.  Can be used in the detection circle, ellipse, curve, arc, and so on.
Hough transform, but if the edge points of the pearl cufflinks, time-consuming, therefore, the system has taken a certain number of randomly selected as the base in five equal portions to the edge of the pearl cufflinks point do Hough Transform, the larger improve the detection efficiency. The defect detection defect detection module is mainly responsible for the detection of defects of the surface of pearl cufflinks. This mens cufflinks event caused uproar.
