Hand-based recognition represents a key biometric technology with a wide range of potential applications both in industry and government. By far, many different hand-based recognition algorithms have been developed. This paper presents a comparative study to evaluate the performance of three state of the art hand-based recognition methods. Using the University of Nevada at Reno (UNR) and the University...
As security is a major concern in present times, reliable authentication systems are in great demand. A biometric trait like the vascular pattern on the back of the hand of a person is unique and secure. A biometric system working on this principle often fails to authenticate a person either because of the varying hand posture or due to an injury altering the vein pattern. In this paper we propose...
Parallel fusion is conventionally defined as a form of complex number for 2-feature. However, it is tough to represent 4-feature parallel fusion due to shortage of mathematical significance. To solve this problem, this paper proposes a reasonable interpretation by introducing quaternion. After parallel fusion whose features are extracted by wavelets decomposition coefficients from the same pixel corresponding...
This paper describes the Iris based authentication system using the Independent Component Analysis (ICA). In this paper, a customized iris extraction algorithm has been applied directly on the unfiltered grayscale image. The polar coordinate system has been used by the researchers for iris processing. Instead, an algorithm based on intrinsic coordinate system has been proposed to save on computation...
