ProFacer
iWatchGuard
Functions and
Operating process:
- Detection - When the system is attached to a video
surveillance system, the ProFacer recognition software
searches the field of view of a video camera for
human faces. If there is a face in the view, it
is detected within a second.
- Alignment - Once a face is detected, the system
determines the head's position, size and pose. A
face needs to be turned at least 25 degrees toward
the camera for the system to register it.
- Normalization -The image of the head is scaled
and rotated so that it can be registered and mapped
into an appropriate size and pose. Normalization
is performed regardless of the head's location and
distance from the camera. Light does not impact
the normalization process.
- Representation - The system translates the facial
data into a binary string - "Faceprint". This coding
process allows for easier comparison of the newly
acquired facial data to stored facial data.
- Matching - The newly acquired facial data is compared
to the stored data and linked to at least one stored
facial representation. As comparisons are made,
the system assigns a value to the comparison. If
a score is above a predetermined threshold, a match
is declared. The operator then views the two photos
that have been declared a match to be certain that
the computer is accurate.
Application:
Surveillance Keeper
ProFacer adds automatic full time face
recognition, matching and active warning alerts to any
new or existing surveillance system. It allows each
camera to serve as a diligent observation point even
when the video is not observed. Face recognition surveillance
incorporates computer intelligence to monitor faces
and match those faces against a “watch
list” face database. As a modern new
tool to identify potential threats to public safety,
ProFacer can scan facial images of individuals and match
them with a database of images containing known suspects.
In seconds, a scanned face can be searched against thousands,
or even millions of database images to determine if
the scanned image matches a previously stored suspect
image.
This creative concept can be applied
to protect the high security areas such as casinos,
banks, computer centers, research institutes and prison
and jails, for fully automatic operation 24 hours a
day. For example, casino starts pilot project using
ProFacer iWatchGuard to identify unwanted guests and
VIPs. Let’s say there is a list of unwanted guests
storing in the database, staff in casino, pays attention
on trailing them from a thousand of guest everyday.
Having installed ProFacer Surveillance Keeper, CCTVs
will be connected and in real time send the scene to
ProFacer detection manager. Inside detection engine,
a number of clear and distinct faces will be identified.
Each face will attempt to match the existing black listed
faces. As soon as a face known to the database appears
in the scene, the system triggers a configurable alarm.
Security guard can locate the unwanted person easily
and take them away. As a result, staffs are no longer
burdened by monotonous work, but can be employed more
flexibly and effectively while still increasing security.
