Image Quality Measures for Fingerprint Image Enhancement
Fingerprint image quality is an important factor in the performance of Automatic Fingerprint Identification Systems(AFIS). It is used to evaluate the system performance, assess enrollment acceptability, and evaluate fingerprint sensors. This paper presents a novel methodology for fingerprint image quality measurement. We propose limited ring-wedge spectral measure to estimate the global fingerp...
متن کاملImpact of Image Quality on Performance: Comparison of Young and Elderly Fingerprints
Performance of fingerprint recognition systems is heavily influenced by the quality of fingerprints provided by the user. Image quality analysis is traditionally performed using local and global structures of fingerprint images like ridge flow, analysis of ridge-valley structures, contrast ratios etc. With large scale deployment of fingerprint recognition in systems like US VISIT program, image...
متن کاملA Review of Schemes for Fingerprint Image Quality Computation
Fingerprint image quality affects heavily the performance of fingerprint recognition systems. This paper reviews existing approaches for fingerprint image quality computation. We also implement, test and compare a selection of them using the MCYT database including 9000 fingerprint images. Experimental results show that most of the algorithms behave similarly.
متن کاملA Hybrid Method for Fingerprint Image Validity and Quality Computation
Fingerprint based system reliability is critical for image validity and quality. As, good quality images make the system performance more robust. However, it is always very difficult to obtain good quality images in practice and image quality degradation leads to invalid images. A hybrid method for fingerprint image validity calculation is proposed that combines validity check, using statistica...
متن کاملAdaptive fingerprint image enhancement with fingerprint image quality analysis
Accurate minutiae extraction from fingerprint images is heavily dependent on the quality of the fingerprint images. In order to improve the performance of the system, much effort has been made on the image enhancement algorithms. If the preprocessing is adaptive to the fingerprint image characteristics in the image enhancement step, the performance gets to be more robust. In this paper, we prop...
متن کاملFingerprint Image Quality Classification Based on Feature Extraction
Fingerprint recognition technology has been widely used in criminal investigation, attendance system, security testing and other fields and has become one of the most mature biometric technologies. Since fingerprint image quality affects heavily the performance of fingerprint recognition system, accurate evaluation of fingerprint image quality has great value in improving the performance of aut...
