Question:- How Automated Fingerprint Recognition System works? Answer:- AUTOMATED FINGERPRINT RECOGNITION- 🖊 During the enrollment phase, the sensor scans the user’s fingerprint and converts it into a digital image. The minutiae extractor processes the fingerprint image to identify specific details known as minutia points that are used to distinguish different users. Minutia points represent locations where friction ridges end abruptly or where a ridge branches into two or more ridges. A typical good-quality finger- print image contains about 20-70 minutiae points. 🖋The actual number depends on the size of the sensor surface and how the user places his or her finger on the sensor. The system stores the minutiae information, location and direction along with the user’s demographic information as a template in the enrollment database. How to match? 🖋 During the identification phase, the user touches the same sensor, generating a new fingerprint image called a query print. Minutia points are extracted from the query print, and the matcher module compares the query minutia set with the stored minutia templates in the enrollment database to find the number of common minutia points. 🖋Due to variations in finger placement and pressure applied on the sensor, the minutia points extracted from the template and query fingerprints must be aligned, or registered, before matching. After aligning the fingerprints, the matcher determines the number of pairs of matching minutiae-two minutia points that have similar location and directions. The system determines the user’s identity by comparing the match score to a threshold set by the administrator. -------------------------- #fingerprint #crimescene #crimesceneinvestigation #criminology #criminalistic #forensicstudy #forensicevidence #forensicscience #forensics #forensic #forensicfield #forensicscientist #automatedfingerprintsystem #AFR #forensicandcriminology #forensicmethods #fingerprinting #forensicworld #forensicbasic #forensicinvestigation https://www.instagram.com/p/B2ycFk-BGMg/?igshid=1gvzu5zm8a50t
