Image Capture Module

The Image Capture Module performs several functions. It calibrates the Veridicom fingerprint sensor, chooses the default sensor settings, and performs sensor diagnostics. It then captures the image as presented to the fingerprint sensor for storage in an image array. The output of this module is a 300 x 300 pixel, grayscale image at 500 dpi.

Automatic Gain Control Module (AGC)

This module enhances the Image Capture Module functions. It automatically adjusts the sensitivity of the Veridicom fingerprint sensor to create the best image for wet, dry, or difficult-to-read fingers. It performs automatic gain control on a column-by-column basis, to obtain images of uniformly high contrast and low noise. New DFX (Difficult Finger Extraction) technology incorporated into the AGC module produces clean, quality images of even the driest fingers. By eliminating background noise and applying a gain factor to the image, DFX minimizes broken or merged ridges caused by dry or wet fingers.

Image Quality Module

This module provides feedback on the quality of the captured image. It produces error codes such as incorrect image position (high, low, left, right); no finger present; or finger too dry or too wet.

Image Enhancement Module

This module takes the captured grayscale image and reduces image noise, enhances the ridges, and binarizes the image. The output of this module is a clean, binary image.

Minutia Extraction Module

This module finds the minutia (ridge endings and bifurcations) and extracts only the significant minutia, eliminating noisy minutia and borders. It creates a template of less than 300 bytes for use with the Fingerprint Verification Module.

Fingerprint Verification Module

This module performs a one-to-one verification of the captured fingerprint minutia with the stored minutia template for that individual. It scores the result and provides statistics on the match. By focusing on the analysis and recognition of fingerprints based on real-world data, Sense Technologies Inc.™ verification software has higher reliability than existing systems while improving on speed and memory performance. It optimizes for the best "false rejection" performance while satisfying market requirements for "false acceptance" error rates.
