Embodiment Construction
[0052] The present invention will be further described below in conjunction with the accompanying drawings.
[0053] refer to Figure 1 to Figure 8 , a quadruple finger comparison method based on feature point set segmentation and RST invariant features, comprising the following steps:
[0054] 1) Carry out the cutting based on the statistical histogram of the set of co-reference feature points;
[0055] 1.1) Calculate the statistical histogram of the quadruplet finger feature points with respect to the X coordinate. Since the joint finger image is much larger than the general fingerprint image, as shown in the reference figure 2 . Especially when taking pictures with a high-resolution scanner or a high-definition camera, the value of the X coordinate of the feature point is relatively large, which can reach more than 2000. For example, refer to image 3 . In order to speed up the processing speed and facilitate the calculation, when the histogram of the X coordinate is ...
