Implementing Fusion Technique Using Biorthogonal Dwt to Increase the Number of Minutiae in Fingerprint Images
Algorithm 1
Determining the angle of rotation between two feature points sets by clustering.
1. The vector H is defined with 360 elements, all elements are initialized with 0, t =0, tm represents the number of all possible lines in the reference image.
2. A pair of points is randomly selected Pr1 and Pr2 in the reference image and their homologous Pt1 and Pt2 in the test image.
3. The angle of rotation θ of the line Pr1Pr2 to have the same orientation as the line Pt1Pt2 is determined.
4. Small value ε is defined.
5. If then ++H[θ].
6. Increment t.
7. If t > tm then go to step 8, otherwise go to step 2.
