1 OverviewCFASII is a Web interfaced Face Indexing & Matching platform.

It allows centralized or de-centralized architecture.

It combines several matching and detection algorithms in order to allow best matching results.

It allows multi-sensor environment to supply Face Recognition, Video Surveillance and License

plate detection.

CFASII supports multiple databases with unlimited number of registered faces. It supports data

export/import actions, enrollment from static images or video, and real-time alerts.

CFASII can "listen" to predefined cameras, collect / match face information and generate

matching reports. CFASII acts as control center and allows "VACAM SD" clients to connect as

de-centralized processing points. It allows real-parallel processing using smart client side

detectors.

2 Limitations2.1 Environment

FRS algorithm should be used in constant lighting conditions for best performance. It is recommended to use two templates: Day & Night. Lighting must be equally distributed on each side of the face and from top to bottom. There should be no significant direction of the light or visible shadows. Care must be taken to avoid "hot spots". These artefacts are typically caused when one, high

intensity, focussed light source is used for illumination.

2.2 PoseFrontal Pose: 15 degrees from frontal in every direction


10/31


2.3 Face ConditionBeard, moustache and other changeable face features sometimes influence face recognition similarity

level. If you want better performance, please include face with beard and cleanly shaved face enrolled

with identical ID.

2.4 EyeglassesThere should be no lighting artefacts on eyeglasses. This can typically be achieved by increasing the

angle between the lighting, subject and camera to 45 degrees or more. If lighting reflections cannot be

removed, then the glasses themselves should be removed. (However this is not recommended as face

recognition typically works best when matching people with eyeglasses against themselves wearing the

same eyeglasses). Glasses have to be of clear glass and transparent so the eyes and irises are clearly

visible. Heavily tinted glasses are not acceptable.

2.5 Identification distanceIdentification distance is not limited while the image quality remains. The face will be recognized only if

the minimal distance between two eyes will be at least 40 pixels.

Not Recommended face position for matchin/enrollment

5.1.4 Tools:

Two algorithms are used to make the face enrollment. The first algorithm is used through detector1 and

the second trough detector2.

Detector1:

Detector1Power Significance of the Detector 1 in the calculation of the Score (0.0-1.0 value).


25/31


Determine Rotation Angle Enables or disables the detection of face rotation angle. Setting this option

to "true" will allow better results with the price of lower performance.

Face Detection Threshold The parameter allows adjusting the sensitivity of the detection. If the

threshold value is set to a higher value, the detector will only recognize faces with sharp, clearly defined

details, thus reducing the number of false positive detections. Setting the threshold lower allows

detecting more faces with less clearly defined features at the expense of increased number of false

positives.Face Resize - Select higher value to increase detection quality, or lower value to improve the

performance.

FAR Value - This parameter allows adjusting the threshold value to determine if two matched templates

belong to the same person. The threshold is calculated at a given FAR (False Acceptance Rate) value. The

FAR determines the acceptable error rate when two different peoples templates are mistakenly

recognized as the same person. Decreasing FAR leads to an increase in FRR i.e. with low FAR it

becomes more probable that two templates from the same person will be determined as belonging to

different people. This value varies from 0.0 (means 0%) to 1.0 (means 100%).

Handle Rotations This parameter can be set to True or False. While it is set to True, it extends default

face rotation angle from -15...15 degrees to -30..30 degrees. It is worth noticing, that extended rotation

support is enabled at the cost of detection speed (3 times performance hit).

Detector2:

Face Confidence Threshold - Specifies the threshold which is considered when looking for faces in an

image. For each face candidate confidence parameter is calculated. With higher threshold value faces

are selected more strictly by the face detection method.

Face Quality Threshold - Identifier specifying the threshold which is considered when extracting facial

features from the image. With higher threshold better quality of face image is required to successfully

extract facial features. The value of this parameter can be in range [0...255]. The default value is 128.

Flip Video Image Horizontally - Flips image horizontally.

Maximal IOD Identifier that specifies the maximum distance in pixels between the eyes. Faces which

have greater distance between the eyes than this parameter won't be returned by the face detection

methods.

Max Roll Angle Deviation - Identifier specifying the maximum roll angle deviation from frontal face in

degrees. The value of this parameter can be in range [0...180]. The default value is 15.

Minimal IOD - Identifier that specifies the minimum distance in pixels between the eyes. Faces which

have smaller distances between the eyes than this parameter won't be returned by the face detection

methods. Recommended value: 65. Setting this value to a number lower then 65, will affect system

accuracy.

General Settings:

Application Path The path of the application.

Application Name IIS application folder nameLowest Value Of Red Zone The lowest value of the Red zone at matching.

Lowest Value Of Yellow Zone The lowest value of the Yellow zone at matching.

Max Best Results The number of the best results that will be displayed when Match is used.

Report Logo Path The location of the logo that will be displayed on every report window.

Server Name The IIS name of the server.

Similarity Filter Value in range 0..100. Only results with score, which is higher than this value, will be

shown.

Identities: CFASII has the ability to predefine identities watch list.

1. Find Find an identity within the database by a certain value.

Select the value by which to perform the search, from the dropdown list. Type in the value and click

Find. All the identities with the same value will be displayed. You can browse through them with

the arrows buttons.

2. Create New Identity Create a new identity by filling all the fields and clicking the Save button.3. Remove Identity Remove the selected identity.4. Close Close this window.5. All Identities Report Display a report showing all the identities created for this database. If

more than one database is open, the system will ask which database to create a report for.

6. Show Identities Report Show the selected identitys report.7. Export Export selected identity.

At least 2 databases have to be opened. If two databases have been opened, the identity will be

exported to the second database. If more than two databases have been opened, the application

will ask you to select the database/databases you want the identity to be exported to.

8. Export All Export all identities to a different database.At least 2 databases have to be opened. If two databases have been opened, the identity will be

will prompt you to select the database/databases you want the identity to be exported to.

9. First Go to first identity.10.Prev Go to previous identity.11.Next - Go to next identity.12.Last - Go to last identity.13.Edit Edit identity. After selecting this, this button will be changed to Save button. After editing

fields, select it again to save.

14.Load All Faces Load all faces assigned to the current identity.15.Assign Faces Assign faces to the selected identities. Select the needed Image/Images from the

explorer window and click Open. The images are added to the identity.

16.Remove Faces Remove the unneeded faces from the selected identity. Select the unneededImage/Images from the explorer window and click Done.

17.Auto Assign Find automatically all the faces matching this identity. At least one face has to beassigned to the identity in order to do so. The more faces assigned, the better the auto assign will

locate all identities faces. Select all the needed faces and click Done.
