Fingerprint Orientation Refinement through Iterative Smoothing
We propose a new gradient-based method for the extraction of the orientation field associated to a fingerprint, and a regularisation procedure to improve the orientation field computed from noisy fingerprint images. The regularisation algorithm is based on three new integral operators, introduced and discussed in this paper. A pre-processing technique is also proposed to achieve better performa...
متن کاملA robust iterative refinement clustering algorithm with smoothing search space
Iterative refinement clustering algorithms are widely used in data mining area, but they are sensitive to the initialization. In the past decades, many modified initialization methods have been proposed to reduce the influence of initialization sensitivity problem. The essence of iterative refinement clustering algorithms is the local search method. The big numbers of the local minimum points w...
متن کاملFingerprint Ridge Orientation Modeling
In the last decade, automatic fingerprint based personal authentication has matured to the point where it can be successfully applied in a myriad of applications. These applications are ranging from the low cost door opener for private use up to the critical government application ensuring national security. One common ground of all this fingerprint based personal authentication systems is the ...
متن کاملFingerprint Orientation Field Enhancement
This paper presents a new method to enhance the fingerprint orientation image. Orientation, as a global feature of fingerprint, is very important to image preprocessing methods used in automatic fingerprint identification systems (AFIS). The most popular, gradient-based method is very sensitive to noise (image quality). Proposed algorithm is an application of gradient-based method combined with...
متن کاملImproving liquid state machines through iterative refinement of the reservoir
Liquid State Machines (LSMs) exploit the power of recurrent spiking neural networks (SNNs) without training the SNN. Instead, LSMs randomly generate this network and then use it as a filter for a generic machine learner. Previous research has shown that LSMs can yield competitive results; however, the process can require numerous time consuming epochs before finding a viable filter. We have dev...
