Fingerprint image enhancement: Algorithm and performance evaluation
- IEEE TRANSCATIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE
, 1998
"... A critical step in automatic fingerprint matching is to automatically and reliably extract minutiae from the input fingerprint images. However, the performance of a minutiae extraction algorithm relies heavily on the quality of the input fingerprint images. In order to ensure that the performance of ..."

Quality Measures of Fingerprint Images
- IN: PROC. AVBPA, SPRINGER LNCS-2091
, 2001
"... In an automatic fingerprint identification system, it is desirable to estimate the image quality of the fingerprint image before it is processed for feature extraction. This helps in deciding on the type of image enhancements that are needed and in deciding on thresholds for the matcher in the ca ..."

An algorithm for fingerprint image postprocessing
- In Proceedings of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers
, 2000
"... Most of the current fingerprint identification and verification systems perform fingerprint matching based on different attributes of the minutia details present in fingerprints. The minutiae (i.e. ridge endings and ridge bifurcations) are usually detected in the thinned binary image of the fingerpr ..."

Classification of Fingerprint Images
- PROCEEDINGS OF THE 11TH SCANDINAVIAN CONFERENCE ON IMAGE ANALYSIS, KANGERLUSSUAQ
, 1999
"... Automatic fingerprint identification is one of the most important biometric technology. In order to efficiently match fingerprints in a large database, an indexing scheme is necessary. Fingerprint classification, which refers to assigning a fingerprint image into a number of pre-specified classes, p ..."

Segmentation of fingerprint images
- ProRISC 2001 Workshop on Circuits, Systems and Signal Processing
, 2001
"... Abstract — An important step in an automatic fingerprint recognition system is the segmentation of fingerprint images. The task of a fingerprint segmentation algorithm is to decide which part of the image belongs to the foreground, originating from the contact of a fingertip with the sensor, and whi ..."

FINGERPRINTS IMAGE COMPRESSION BY WAVE ATOMS
"... The fingerprint images compression based on geometric transformed presents important research topic, these last year’s many transforms have been proposed to give the best representation to a particular type of image “fingerprint image”, like classics wavelets and wave atoms. In this paper we shall p ..."

Efficient Gradual Segmentation of Fingerprint Images
- Proceedings of Sixth WSEAS International Conference on Multimedia Systems and Signal Processing
, 2006
"... Abstract:- A new algorithm for fingerprint image segmentation is presented. Gradual segmentation algorithm and multi segmentation features are used to segment fingerprint image in two steps. First we get the whole fingerprint region from image, and then the well-defined region and recoverable corrup ..."

Fingerprint image: pre- and post-processing
"... Abstract: Automatic Fingerprint Identification Systems (AFIS) are widely used for personal identification due to uniqueness of fingerprints. Minutiae-based fingerprint matching techniques are normally used for fingerprint matching. Fingerprint matching results and their accuracy depends on presence ..."
