How Is the Face Imaged ?

Facial images can be captured either through a live scan or through the use of photographs or video. Some algorithms will not support the use of a photograph or video image, as depth and other types of measurements are required. If a photograph is imaged, then a high-quality scanner is used and the photo is processed into a facial template. While infrared cameras are used for facial imaging, they are not considered here since they are not suitable for use as network security biometric devices. Their price point and size make them currently impractical to use and deploy.

Cameras that are currently usable for network security access are generally the same ones used for desktop video conferencing. They are low in cost since they use popular CCD and CMOS image technologies. They are also small enough to be deployed on a desktop. Also, they do not require any special imaging boards and they support standard connections like USB.
