Miniature and Orientation Map Feature Extraction
Abstract
Biometric identification involves using a person's unique physical characteristics, such as fingerprints, face recognition or iris, to identify them. Fingerprint recognition is the most used biometric method, as each person's fingerprints are unique. In this process, features are extracted from fingerprint images based on the ridges and edges present in the images. Supervised learning techniques are then used to recognize the palm print images. The features are then recognized using distance metrics. Fingerprint recognition is efficient compared to other methods, and its performance can be measured using metrics such as true positives, true negatives, false positives, false negatives, sensitivity, specificity, and accuracy. The Minutiae and Orientation map features are also extracted from fingerprint images to aid identification. The Minutiae feature extraction helps identify significant ridges and corners, while the Orientation map features texture-based information. Matching fingerprints is based on measuring the distance between the extracted features. Accuracy, Specificity, and Sensitivity are used to gauge the process' performance.

Submission of an original manuscript to the Journal of Computing Technologies and Creative Content (JTeC) will be taken to mean that it represents original work not previoussly published, that it is not being considered elsewhere for publication. All submitted articles that are published by JTeC cannot be published anywhere by the authors unless with the permission by JTeC Editors. JTeC reserves the right to the publications of the articles it published, and reserves the right to reuse the articles elsewhere for academic purposes, while still retaining the names of the original authors with the original articles.
JTeC takes the stance that the publication of scholarly research is meant to disseminate knowledge and in a not-for-profit regime, benefits neither publisher nor author financially. It sees itself as having obligation to its author and to society to make content available online now that the technology allows for such possibility.
