Imagine you’ve come home from a long day at work. You get out of your car, sling your bag over your back, and think about the delicious meal that you’re going to eat for dinner. Just as you approach the door to your amazingly comfortable home, you realize that something is wrong – you’ve forgotten your keys and have exhausted all other options. Maybe you’re on route to board a plane to go to a very important meeting abroad and you realize that you’ve forgotten your ticket, and it’s too late to turn back. What do you do?
Fortunately, Facial Recognition technology could be the answer, and may not be as far off as we think. With just a simple computer device to scan your face, you may be able to have instant access to your house without even having to use a key, or to your ticket without even having it present. Facial recognition software has the potential to improve the security of an individual, whether it be financially, physically, or just for pure convenience sake -- and it’s already deep into development and use in other countries. Within the next decade or so, we should be looking forward to seeing this technology being used in everyday life.
Facial recognition technology works as a technological application through a computer source which can both identify and verify the identity of a person through a digital image. We see this sort of technology utilized in crime shows where a face can be crossed referenced to match a potential suspect – that’s the sort of thing we’re looking at for everyday life, security and convenience. But how does it work? Through a series of algorithms, Bonsor and Johnson (2001) explain that “3D facial recognition uses distinctive features of the face – where rigid tissue and bone is most apparent (…) to identify the subject”. However, the process isn’t as simple as it may seem on the surface.
The algorithm utilized goes through a series of steps to ensure complete accuracy. The first step is detection, where a picture of the subject must be acquired – whether it be through 3D surveillance or a simple picture of the subject. The second step is alignment, where the characteristics of the subject’s head is determined, including defining features such as the nose and eyes. The third step is measurement, which is where the curves and the scale of the face are measured to absolute precision. Then, for the fourth step, the images are translated into a code, which will then be used towards the fifth step, which is where the image is presented to a database of images to find a match. The final step is verification and identification, where the image is verified to be a precise match of the correct subject. As simple as it may seem, facial recognition technology isn’t very cut and dry – it goes through a multitude of process, all of which that are of equal importance. This technology is interesting because in the future, it can provide convenience and improved security that can positively affect our everyday...
