Abstract:
Biometry in the field of identifying people is a highly topical theme these days. The most widespread area is identification of a person on the basis of fingerprints, nevertheless scanners of the bloodstream, iris and retina in particular are undergoing development, as well as identification on the basis of facial features. In the case of scanners which distinguish people according to their face, user problems are appearing. One of these problems is the surrounding environment of the scanner device, in particular light conditions. According to tests, it is necessary to conduct identification of people under laboratory conditions, which is not acceptable from the user perspective. It is essential to consider this problem and to innovate and extend the system for identification on the basis of facial features. It is necessary for the system to react, if possible, with a minimal error rate and within the fastest response time. Through the help of testing light conditions, an improvement was achieved in the capability of identifying facial features, and at the same time a further modification was proposed to perfect the existing technology.
Key words:
