If you have a computer with camera Web and it would like to take to a registry of the time of arrival and exit of people, this article explains to him how to do it. A biometric control system is a set of software and hardware. This system when being based on the recognition of the face is called Control of Face Biometric Attendance. Hardware is in charge to obtain the biometric readings. In this case, webcam, that one is in charge to capture the images of the face of the person.
For this Control of Face Biometric Attendance we needed the possible clearest image we will obtain that it with one webcam of 1 Mega Real pixels of Resolution (without interpolation by software), the majority of the portable computers of average range that incorporate webcam fulfills this requirement. Software is in charge to read and to process the biometric reading. In this case, it detects when a person is against webcam, locates its face, reads and looks for the unique characteristics of the face (the distance between eyes, size of eyes, width of the mouth, distances to eyes – mouth, etc.), that are really those that differentiates a person from another one. These unique characteristics keep in a data base and are those that allow software to identify the person and to register the date and hour in which I am realised the biometric reading. A software that realises these processes is i-Phase Planigrafo, can find major information in the Web site of Planigrafo.com in the following Link. The traditional systems of attendance control with track reader sometimes they present/display problems when the tracks or the reader are dirty, the tracks are of low quality for the reader or the fingers are droughts. With the control system of Face attendance these problems are eliminated, it is only needed that the person watches at the camera after seconds and ready. This system for being of easy implementation, economic and not to require the direct physical contact with the people, it is a real alternative for the small ones and medians social companies and surroundings of average traffic.
