Image restoration of skin scattering and optical blurring for finger vein recognition

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

“…In image restoration, a depth-dependent point spread function (DPSF) (Lee and Park, 2011) and a scattering removal method based on a biological optical model are proposed, to remove scattering occurrence in biological tissue during imaging. Some image enhancement methods, such as even-symmetric Gabor filter (Yang and Shi, 2014), circle Gabor filter (Yang et al, 2009) and multiscale matched filter (Gupta and Gupta, 2015), are introduced to sharpen the image contrast and enhance some blurred finger veins.…”

Face and palmprint multimodal biometric systems using Gabor–Wigner transform as feature extraction

“…Biometrics also offers some advantages over these security measures such as non-repudiation, accuracy and security. Numerous biometric recognition systems have been proposed based on different biometrics [3][4][5][6][7][8][9]. Recently, several studies reveal that the walking pattern of a person can also be used for recognition purpose [7].…”

Palm Vein Verification Using Multiple Features and Isometric Projection

“…It is difficult to counterfeit veins using forged vein patterns. The palm vein recognition systems are widely used because the recognition accuracy is very high [1]. The speedy growth in the use of e-commerce applications requires faithful user identification for effective and secure access control [2].…”
