мда. Похоже мы читаем разные вещи. Вот что написано в том, на что вы дали мне ссылку:
how it works
Biometric security on your iPAQ Pocket PC works in two basic steps: fingerprint enrollment and
fingerprint verification. Fingerprint enrollment involves fingerprint acquisition and image
reconstruction, fingerprint image processing and feature extraction, fingerprint image quality
evaluation, and template generation. Fingerprint verification involves fingerprint acquisition and
image reconstruction, fingerprint image processing and feature extraction, fingerprint image
quality evaluation, template generation, and template matching.
enrollment
Enrollment is the process of collecting, processing, and registering reference versions of the
fingerprints of the person authorized to use the secured device, in this case, the iPAQ Pocket PC.
This is the initial step. The user is guided through the process for selecting one or more fingers to
enroll and swiping the selected fingers across the FingerChip sensor to capture associated
fingerprint images. Enrollment assesses the quality of the captured images and directs the user, as
required, to repeat the swiping activity until adequate images are obtained. This process may
require several attempts to ensure good prints are captured. A dataset is extracted from the images
for each finger enrolled. These datasets are the reference templates used to ensure that only the
authorized user is allowed to logon to your iPAQ Pocket PC during verification. The iPAQ Pocket
PC enrollment process includes user training designed to teach proper swiping of fingers across
the FingerChip sensor.
