Face Recognition Systems

All humans have tiny ridges and valleys of skin on their fingertips, formed through a combination of genetic and environmental factors, building unique fingerprints for each human being. Even identical twins have unique fingerprints. Such unique biometric traits set the platform to build fingerprint recognition systems. Over the several years of advancement in finger recognition technology, several types of fingerprint sensors like Optical, Ultrasonic, Passive capacitance, Active capacitance etc. were industrialized. Optical fingerprint sensors use imaging technology, capturing a digital image of the print using visible light.
