Problems solved by technology

Fingerprint quality metrics used within enrollment and AFIS / companion applications are generally not suitable for this preflight capability due to the requirement for full resolution scans of the fingerprint image (typically at 500ppi and 1000ppi)

Abstract

A ridge flow based fingerprint image quality determination can be achieved independent of image resolution, can be processed in real-time and includes segmentation, such as fingertip segmentation, therefore providing image quality assessment for individual fingertips within a four finger flat, dual thumb, or whole hand image. A fingerprint quality module receives from one or more scan devices ridge-flow-containing imagery which can then be assessed for one or more of quality, handedness, historical information analysis and the assignment of bounding boxes.

Description

[0001] This application claims priority to US Patent Application Serial No. 60 / 795,215, entitled "Real Time Fingerprint Quality and Segmentation," filed April 26, 2006, which is incorporated herein by reference. technical field [0002] The present invention generally relates to quality identification and segmentation. More specifically, an exemplary aspect of the invention relates to the quality and segmentation of biometric image information, such as fingerprint, handprint or footprint image information. Background technique [0003] The instant scan device provides a preflight mode of operation that acts as a preflight to help the operator with finger orientation and image fidelity. Due to processing power, timing constraints, and bandwidth requirements, these devices and their associated quality metrics do not provide outputs that can be correlated with enrollment applications or other more complex quality measurements used by Automated Fingerprint Identification Systems...
