Biometrics has been getting more interests in the recent decade as a method of personal identification system. It identifies a person by recognizing the unique physiological or behavioral characteristics of a person. As a new biometric system, finger crease pattern identification system is under development. For the algorithm, the extraction of exact finger area is essential. In this paper, a new boundary tracking algorithm for extracting finger area, which can be utilized by a finger crease pattern recognition algorithm, is proposed. Due to noise and irregular illumination, conventional algorithms for boundary tracking such as skeleton-based tracking methods were not suitable for typical image of hand, So I proposed a finger boundary tracking algorithm utilizing a boundary-point-detection mask. We have observed that the proposed method provides stable and optimized boundary tracking.

This paper proposes an hybrid person identification algorithm utilizing finger crease pattern and finger thickness profiles which is assumed to improve the performance of the person identification algorithm utilizing only finger crease pattern. We tracked boundaries of the fingers and computed the thickness of the boundaries, thereafter performed the verifications of a person by matching one dimensional profiles of finger crease and finger thickness profiles together. This algorithm shows the possibility of an hybrid biometrics identification system. Lastly, the comparative evaluation on our system and the other algorithm is presented.
