How does facial recognition software work?
"Identix®, a company based in Minnesota, is one of many developers of facial recognition technology. Its software, FaceIt®, can pick someone's face out of a crowd, extract the face from the rest of the scene and compare it to a database of stored images. In order for this software to work, it has to know how to differentiate between a basic face and the rest of the background. Facial recognition software is based on the ability to recognize a face and then measure the various features of the face. Every face has numerous, distinguishable landmarks, the different peaks and valleys that make up facial features. FaceIt defines these landmarks as nodal points. Each human face has approximately 80 nodal points. Some of these measured by the software are: * Distance between the eyes * Width of the nose * Depth of the eye sockets * The shape of the cheekbones * The length of the jaw line These nodal points are measured creating a numerical code, called a faceprint, representing the face in the database.In the past, facial recognition software has relied on a 2D image to compare or identify another 2D image from the database. To be effective and accurate, the image captured needed to be of a face that was looking almost directly at the camera, with little variance of light or facial expression from the image in the database. This created quite a problem."--How Stuff Works
How you can explain that nodal points are located one-half of the wavelength of the interfering waves from one to another?
The zeros (nodal points) of a sinusoidal wave occur every half-wavelength of the sinusoidal wave.
What Facial recognition?
Going on the assumption that this is a reference to the Facelt, it is a software program that is used to identify persons whose facial ID's are stored in a databank. This is done using a very sophistcated process of matching 14-22 out of 80 nodal points of a human face. Some of the "points" being distance between the eyes and the line of the jaw. This is a simplistic definition of how the system works. It is much more complexed than can be easily explained, and some information is only available to authorized personnel.AnswerAttrasoft also makes such a program. Google that name to find it. AnswerFacial Recognition is a biometric technology use face as a verification medium us for security applications at business, offices, corporates and organizations. Facial Recognition can be easily integrate with Face Recognition Time attendance system, Visitor Management System, face recognition access controls like door locks.
