Fingerprint Singular Point Detection Algorithm by Poincaré Index

چکیده
Fingerprint indexing is an efficient technique that greatly improves the performance of Automated Fingerprint Identification Systems. We propose a continuous fingerprint indexing method based on location, direction estimation and correlation of fingerprint singular points. There have been many approaches introduced in the design of feature extraction. Based on orientation field, Firstly, we divide it into blocks to compute the Poincaré Index. Then, the blocks which may have singularities are detected in the block images. Experiment show the present algorithm is robust than the traditional method on poor quality images. Key-words: Fingerprint Core Delta Point Orientation Poincaré Index

Fingerprint Singular Point Detection via Quantization and Fingerprint Classification
This paper aims to present a fingerprint singular point detection algorithm and a rule-based fingerprint classification method. The singular point detection algorithm uses a quantization approach on the orientation field of the fingerprint image and seeks to locate the core and delta points via the changes of the gray levels around a 2x2 window. It has been found that with the application of an...
متن کاملAn Adaptive Approach to Singular Point Detection in Fingerprint Images
This paper presents a novel algorithm for detection of singular points, the core and delta points, in fingerprint images. The number and location of singular points, are used to classify fingerprint images in to five general groups; and therefore to narrow down the search space in large fingerprint databases. Using the proposed directional masks in the first step, detects the neighborhood of th...
متن کاملAnalysis of Singular Points in Fingerprints based on Topological Structure and Orientation Field
As an important feature of fingerprints, singular points ( core and delta) not only represent the local ridge pattern characteristics, but also determine the topological structure (i.e. fingerprint type) and largely influence the orientation field. In this paper, we have performed analysis for singular points in two aspects: (1) based on the topology theory in 2D manifold, we deduced the relati...
متن کاملSystematic Methods for the Computation of the Directional Fields and Singular Points of Fingerprints
ÐThe first subject of this paper is the estimation of a high resolution directional field of fingerprints. Traditional methods are discussed and a new method, based on principal component analysis, is proposed. The method not only computes the direction in any pixel location, but its coherence as well. It is proven that this method provides exactly the same results as the aaveraged squaregradie...
متن کاملSingular Point Detection in Fingerprint Image
Singular point detection is an important task in many Automatic Fingerprint Identification Systems (AFIS). There already exists many singular point detection algorithms, Most of them can efficiently detect the core point when the image quality is fine, but when the image quality is poor, the efficient of the algorithm degrades rapidly. In this paper, we present a new singular point detecting al...
