Residual orientation modeling for fingerprint enhancement and singular point detection

A spatial domain scar removal strategy for fingerprint image enhancement

“…Though Curved Gabor filter is doing a better job while dealing with scars but comes with a heavy computa-125 tional price tag. Apart from these three classical techniques, there are other enhancement methodologies specifically suggested for fingerprint image enhancement such as Chikkerur [16], ROM [17], TwoStep [18], Oriented Deviation based [19], Improved Gabor-based [20] and Genetic approach [21], present 130 in the literature. They do have their unique merits, but they did not take up the scar issue.…”

Finger-vein pattern restoration with Direction-Variance-Boundary Constraint Search

“…Biometric personal identification techniques, such as fingerprint (Jirachaweng et al, 2011), facial (Wang and Wu, 2010), iris (Roy et al, 2011), and vein pattern recognition (Wang et al, 2008), have attracted increased attention on various platforms with higher security and lower identification error rate requirements. Among these techniques, finger-vein verification has been paid growing attention in the biometrics community, because fingervein features hold the merits of uniqueness, stability and anticounterfeit .…”

Applying Multifractal Spectrum Theory to Fingerprint Features Recognition

“…Compared with the minutiae characteristics, the orientation field is more stable in the process of fingerprint feature extraction and feature matching. In recent years, the orientation field features of fingerprints had been studied by many researchers [1][2]. The orientation field of fingerprints is usually defined as the local orientation of ridge and valley.…”
