5. Conclusion
Old matching methods and even those are still being used, have
time-consuming procedures with no respect of hardware limitations.
However, the methods based on fingerprint ridge direction
pattern do not suffer from this problem. Another significant benefit
of the proposedmethodis the use of ergodic topology forHMM.This
approach overcomes the deficiencies of the formerHMMmatching
algorithm.
In general, the preferences and contributions of our proposed
HMM matching method to the previous one should be considered
as follows
