What is the process behind facial recognition CCTV?

Facial recognition is a type of biometric software that allows its users to identify an individual by using an image that is digital. The technology tracks the facial characteristics of individuals being identified mathematically, and saves their data in databases. Biometric face recognition’s algorithms for mathematical analysis typically adhere to these steps of image processing in only a few seconds:


There are many distinct features that can be seen in the facial features of every person The first step the system performs is to collect the physical or behavioral characteristics of the specified region. Most often, these samples are taken under predefined conditions over the time frame.


Once all the information needed is collected, the samples will be sorted out individually. By analyzing these samples the system will generate templates that will serve as the basis for the next verification process.


After the extraction has completed, the next step of image processing would be the process of comparison. At this point the data gathered will be compared to the current templates. The majority of software measures eye distance as well as the depth of the eye sockets, the size of the nostril, the form of cheekbones, as well as how long the jawline.


After the stage of comparison after the comparison stage, the system of facial detection technology will proceed into the match stage. In this stage, the technology checks that the features recorded are in line with any of the templates that are in the system.
