About

Many would say that the father of facial recognition was Woodrow Wilson Bledsoe. Working in the 1960s, Bledsoe developed a system that could classify photos of faces by hand using what’s known as a RAND tablet, a device that people could use to input horizontal and vertical coordinates on a grid using a stylus that emitted electromagnetic pulses. The system could be used to manually record the coordinate locations of various facial features including the eyes, nose, hairline and mouth.

These metrics could then be inserted in a database. Then, when the system was given a new photograph of an individual, it was able to retrieve the image from the database that most closely resembled that individual. At the time, face recognition was unfortunately limited severely by the technology of the era and computer processing power. However, it was an important first step in proving that face recognition was a viable bio metric.
