Finger knuckle-print biometric system has widely used in modern e-world. The region of interest is needed as the key for the feature extraction in a good biometric system. The symmetric discrete orthonormal stockwell transform provides the computational efficiency and multi-scale information of wavelet transforms, while providing texture features in terms of Fourier frequencies. It outperforms ...

Biometric based Personal authentication is still active research problem due to various issues such as providing high accuracy, computationally less complex feature extraction method and fusion strategy of multiple feature information. In this work we propose a personal authentication system using one such hand based biometric trait, Finger Back Knuckle Surface (FBKS). The texture pattern produ...

Electronics Letters vol. 45, no. 20, September 2009 Personal Identification using Finger Knuckle Orientation Features Ajay Kumar, Yingbo Zhou This paper proposes a novel approach for personal identification using finger images which exploits the orientation features from the random knuckle lines using finite Radon transform. The feasibility of this approach is rigorously evaluated on a publical...

Personal identification approaches using finger knuckle patterns are receiving increasing attention in the biometrics literature. Several approaches have been explored and these methods consider knuckle patterns as textured-like patterns, similar to the iris, and illustrate promising results. However much of the law-enforcement and forensic analysis for hand biometrics still relies on recovery ...

This paper describes the development of a knuckle walking mode of locomotion by a free-living yellow baboon (Papio cynocephalus). Some implications of this occurrence for theories of the evolution of knuckle walking are discussed.

Abstract Objectives This study examines the sensitivity of development dorsal metacarpal ridge (DMR) to frequency knuckle‐walking during ontogeny in chimpanzees, and compares prevalence prominence DMR hominoids baboons. Materials Methods We characterized type quadrupedalism wild chimpanzees different ages from Ngogo community, Uganda. Using museum specimens, we quantified third angle height Pan...

INTRODUCTION Secondary hyperparathyroidism in end-stage renal disease patients has protean musculoskeletal manifestations. Some of our dialysis patients spontaneously vocalized that they had lost the ability to crack their knuckles and then experienced gratifying restoration after surgical parathyroidectomy. We propose that the physiology and mechanical basis of knuckle cracking would be affect...

The automobile's knuckle is connected to the parts of the steering system and the suspension system and it is used for adjusting the direction of a rotation through its attachment to the wheel. This study changes the existing material made of GCD45 to Al6082M and recommends the lightweight design of the knuckle as the optimal design technique to be installed in small cars. Six shape design vari...

Biometric based human recognition is a most obvious method for automatically resolving personal identity with high reliability. In this paper we present a novel finger-knuckle-print ROI extraction algorithm. The basic Gabor filter is modified to Curvature Gabor Filter (CGF) to obtain central knuckle line and central knuckle point which are further used to extract FKP ROI image. Largest public F...

Knuckle biometrics is one of the current trends in biometric human identification which offers a reliable solution for verification. This paper analysis FKP recognition based on the behaviour of two different filtering and classification methods. Firstly, Gabor Filter Banks techniques are applied for finger knuckle print recognition and then the same database is analysed against Dual Tree Compl...
