    Others have tried to reduce the size of the fingerprint by only looking around shot changes. [5] Video fingerprinting does not rely on any addition to the video stream. A video fingerprint cannot be removed, because it is not added. In addition, a reference video fingerprint can be created at any point, from any copy of the video. [6] [7]

    en.wikipedia.org/wiki/Camera_lens

    Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens, photographic lens or photographic objective is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.

  4. Fingerprint scanner - Wikipedia

    en.wikipedia.org/wiki/Fingerprint_scanner

    The measure of the fingerprint image quality is in dots per inch (DPI). [8] Optical scanners take a visual image of the fingerprint using a digital camera. Capacitive or CMOS scanners use capacitors and thus electric current to form an image of the fingerprint. This type of scanner tends to excel in terms of precision.

    At Autoblog’s Tech of the Year, Senior Editor John Snyder demonstrates the steps needed to set up Facial Recognition and Fingerprint on the 2023 fully electric Genesis GV60.

  6. Fingerprint - Wikipedia

    en.wikipedia.org/wiki/Fingerprint

    A fingerprint classification system groups fingerprints according to their characteristics and therefore helps in the matching of a fingerprint against a large database of fingerprints. A query fingerprint that needs to be matched can therefore be compared with a subset of fingerprints in an existing database . [ 4 ]

    en.wikipedia.org/wiki/Biometric_device

    Fingerprint sensors can be found on mobile devices. The fingerprint sensor is used to unlock the device and authorize actions, like money and file transfers, for example. It can be used to prevent a device from being used by an unauthorized person. It is also used in attendance in number of colleges and universities.

  8. Pixel 4a - Wikipedia

    The back houses a capacitive fingerprint sensor centered below the camera lens, which was decently reliable at the time of release. Both have stereo loudspeakers, one located on the bottom edge and the other doubling as the earpiece, the main one being the bottom edge speaker, and a 3.5 mm headphone jack .

  9. Automated fingerprint identification - Wikipedia

    en.wikipedia.org/wiki/Automated_fingerprint...

    Automated fingerprint verification is a closely related technique used in applications such as attendance and access control systems. On a technical level, verification systems verify a claimed identity (a user might claim to be John by presenting his PIN or ID card and verify his identity using his fingerprint), whereas identification systems ...
