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

Question- ✍What is Onychology? ✍What is the use of Onychology in forensic science?

Answer- 👉 Onychology is a Greek word, Onuks = nail, Logia = study of. 👉 Forensic Onychology is the subject which deals with study of fingernails and toenails for better administration of justice in the court of law.

Use of Onychology in Forensic Science:- 👉Nails are important tissues for human identification. One of the major advantages of utilizing nail is that, in comparison with other tissues, sample size and sampling process can be considered relatively non invasive and non destructive and yet each nail retains a discrete record of detailed information on genetic inheritance, drug use, pathology, diet and location history as well as exposure to explosives residues or other pollutants. In contrast to soft tissues, nails survive relatively well in the decomposition environment. ————————— #forensic #fingerprints #criminology #criminalistic #forensic #forensics #forensicscience #forensicexpert #crimesceneinvestigation #crimescenemanagement #crimesceneinvestigation #forensicinvestigation #forensicknowledge #forensicfield #forensicstudy #bloodtest #immunodiffusiontest #ouchterlony #confirmatorytestforblood #forensictest #forensicmethods #Onychology #nails #fingernails #toenails #toxicology #drugdetection https://www.instagram.com/p/B5x9maBpWzO/?igshid=4y5gq9nxsrjr
