The thread of the method of analysis steps are as follows:?

Massive texture is strip, then the pixels in a two opposite directions will be more. So that by the number of pixels in all directions in the statistical outline can be detected thread. By etching operation, the original binary image to reduce the circle, and that deleting the edge contour of the original image. The image of the original image is less corrosion, you can get the edge contour of the original image. Thus, learn the few methods for cufflinks are very necessary.  Shown in Figure 3.6. Circle in Figure 3.6 Corrosion results outline of the image information after it began keeping statistics on the direction of each contour point.
The first image is divided into eight directions, statistical methods start from any point on the contour counterclockwise looking for adjacent points, find the neighboring points in the direction of its corresponding array on record, until the return to the starting point. Statistical finished, and then calculate the percentage of the total points of the number of pixels in each direction, if there are points in two directions, respectively, 25% of the total points - 50%, total points of not less than 50, and able to return to the initial point on the texture detection strip, namely, that the pearl cufflinks thread. This method has a good effect for a wide banded texture, but for smaller stripes, it is easy to make mistakes. For example, Figure 3.7 is 3.6 Enlargement. Anti-fraud tactic one: beware of the palladium mens cufflinks as platinum.
The red pixel edge detection point when the order can be found in the encounter single-pixel connection will not be able to completely traverse the edge points, so it is easy to a miscarriage of justice. Journal of Zhejiang University Chapter 3 thread detection Figure 3.7 Texture fast boundary detection results  thread based on bounding box analysis by a summary of the analysis shows that the effect of the chain link thread detection methods and poor presented here a new thread analysis methods. Mrs. Tan would like to send her husband a platinum mens cufflinks as a wedding anniversary present. The thread of the method of analysis steps are as follows:? By FloodFill identify all points in the connected region of the texture blocks. Calculate the minimum bounding box of the texture blocks.
