Quality measurement of unwrapped three-dimensional fingerprints: A neural networks approach

Abstract: Traditional biometric systems based on the fingerprint characteristics acquire the biometric samples using touch-based sensors. Some recent researches are focused on the design of touch-less fingerprint recognition systems based on CCD cameras. Most of these systems compute three-dimensional fingertip models and then apply unwrapping techniques in order to obtain images compatible with biometric methods designed for images captured by touch-based sensors. Unwrapped images can present different problems with re… Show more

“…They can secure the integrity and preventive access of fingerprints would be a positive direction in the step to deal with the problem posed by acquisition of data. Many sensors demand to move the finger over the buying surface for several seconds, and then wait for a frame to be of acceptable quality to avoid speed of data collection problems [22], [23].…”

“…Moreover, the illumination must be uniform and able to compensate for environmental variations [78]. -Higher quality fingerprint images also increase the performance of fingerprint recognition technologies, and can be obtained by enhancing both the usability of the system and the algorithms for the quality estimation [28,38,24], without increasing the acquisition time. -Less-intrusive iris recognition techniques could help in extending the field of use iris-based systems, since they are currently the most accurate, but have high costs and intrusiveness.…”
