Image enhancement techniques have become more popular among the researchers as it is widely been used in security and medical applications. There have been different image enhancement technique approaches and filters were developed to enhancement the fingerprint images. While analysis a few accesses are established in spatial domain, frequency domain and fuzzy model. These techniques are based on local ridge frequency and orientation. This survey research paper was aimed to analyze these techniques, its effectiveness on fingerprint image enhancement. The study has considered and discussed various available methods and techniques that have been used in the previous research studies and also provides the direction for further research on fingerprint image applications. |
