Many palmprint authentication approaches have been proposed in recent years. Among
them, the orientation based coding approach, in which the dominant orientation features of …

Online palmprint recognition and latent palmprint identification are two branches of
palmprint studies. The former uses middle-resolution images collected by a digital camera in …

Biometric based personal authentication is an effective method for automatically
recognizing, with a high confidence, a person's identity. By observing that the texture pattern …

The evidential value of palmprints in forensics is clear as about 30% of the latents recovered
from crime scenes are from palms. While palmprint-based personal authentication systems …

In this paper, we propose a novel palmprint verification approach based on principal lines. In
feature extraction stage, the modified finite Radon transform is proposed, which can extract …

The development of accurate and robust palmprint verification algorithms is a critical issue in
automatic palmprint authentication systems. Among various palmprint verification …

This paper investigates a new approach for personal authentication using fingerback
surface imaging. The texture pattern produced by the finger knuckle bending is highly …

Subspace learning methods are very sensitive to the illumination, translation, and rotation
variances in image recognition. Thus, they have not obtained promising performance for …

Various palmprint recognition methods have been proposed based on orientation features
of palmprints. Among them, the competitive code method using the dominant orientation of …

Touchless biometrics has become significant in the wake of novel coronavirus 2019 (COVID-
19). Due to the convenience, user-friendly, and high-accuracy, touchless palmprint …
