Facial Recognition

Over the last several decades, the increasing popularity of law enforcement television shows has made the general public become familiar with the concept of facial recognition software. A common plot device for screenwriters looking to introduce a character, facial recognition systems are any device able to identify an individual from a digital image or a frame from a video file. These systems work in several ways and are used in a surprisingly large variety of ways throughout the technological world. For the most part, facial recognition software works on simple, basic programming functions. Algorithms are written and mathematical models are made in order to identify several main facial features in the image being analyzed, which are then compared to images stored in a database of some kind. These programs are becoming more and more sophisticated as time passes, taking note on everything from skin blemishes to bone structure in order to ensure that the wrong images are not matched together. Originally, facial recognition capabilities began to be developed in the early 1960s, by researchers employed by a still unidentified intelligence agency. The original method, as developed by scientists Blesdoe, Chan, and Bisson, was to measure the distance between important features on the face such as the eyes and nose. These distances were then mapped against those stored in the database, allowing a crude if fairly reliable method of facial recognition. Over the next five decades, the ability of facial recognition software to match images of faces together has improved drastically. …
