What Is The Face Recognition?
Face recognition is a biometric application that identifies a particular person with a visual analysis using image processing techniques and after pattern comparison process. Face recognition is generally uses in the security field.
Facial recognition systems work with numeric codes resulting from the analysis of 80 specific points in the face of people called face prints. These specific points are:
- The cheekbones,
- The depth of the eye pits,
- Nose length and width.
These numerical codes are compared with the previously datas in the database to perform the face recognition system.
Environmental conditions may effect this process. If the ambient light is low, a slip on the taken visual cause a trouble.
Facial recognition systems are provided with more accurate operation by three-dimensional modeling with improved technology. Under the suitable conditions, it gives a close to 100% correct result.
Facial recognition systems have become available on the phone with the development of smartphones. In order to open the phone’s lock, the image that was taken when we want to unlock with the previously obtained image information is compared and the lock is opened if it matches.
In the today World, private companies are developing an application that aims to reach the information of a member with a registered photos in their system.
Is Face Recognition Safe?
Facebook uses software to help users tag automatically by using face recognition. This information is kept by facebook when we upload a photograph on Facebook. Thanks to it we can understand whether you are in other photographs.
Let’s suppose that we have a photo on Facebook and think about putting a facial recognition system which use our face at the door of our home.
If we had installed an incapable system, it would not be surprising that our doors would be opened by foreigners with the information in the photo. Facial recognition systems evolve by making deep analyzes through technological developments.
History of Face Recognition
Face recognition system is a new concept. These systems, which were started to be used in 1960, were performed manually by an operator. This operator choose certain points of the face and registers them according to it.
For example, in order to receive eye data, the administrator indicated the location of the eyes. The techniques used here were short-term solutions such as hair color, eye color, and nose length.
In 1988, some people said that data must be retrieved from 100 different parts of the face in order to establish a reliable and unique identity. This technique is improved by making stronger decisions with more powerful software
