The Face detectionDetection object is created on the basis of the Camera object in the Hardware tab of the System settings dialog box.

Configure the Face detection object as follows:

...

.

Image Modified

Set the face search area border on the video image by specifying the required values in percent in the corresponding fields (1), or by clicking the Image Removed button (2) and using the interactive interface.

...

Setting the face search area border is available only if the Tevian or VideoIntellect 1.1 face recognition modules are used.

After you click the Image Removed button, the window with the corresponding video camera image will open.

To set the face search area border, click the Stop video button at the required time, select the required area using the left mouse button, and then click OK.

There are several variations of the face detection operation depending on the setting of the external capture and Face Recognition Server (3):

1. External capture is NOT selected and the detection is NOT added to any of the Face Recognition Server channels. In this case, only capturing of photos of faces detected by Intellect software capturing is performed, and generation of vectors is not performed. This option is not for Face-Intellect.
2. External capture is NOT selected but the detection is added to any of the  the Face Recognition Server channels. In this case, capturing and saving of photos of faces detected by Intellect software capturing, generation of vectors and recording them to database are performed. This option does not allow face recognition (while search and visitor counting are available).
3. External capture is selected but the detection is NOT added to any of the Face Recognition Server channels. In this case, the photos of faces captured by the face recognition modules (see Structure of the Face Intellect software package), are captured and saved, and the vectors are generated, but the vectors are not saved in the database. This option is only suitable for use in scripts.

4. External capture is selected and the detection is added to any of the Face Recognition Server channels. In this case, the photos of faces captured by the face recognition modules (see Structure of the Face Intellect software package), are captured and saved, and the vectors are generated and recorded to the database

The external capture is recommended for use. From the External capture drop-down list select the Face Recognition Server with the help of which the face capturing with the subsequent generation of a vector (if the Create FIR in detection unit checkbox is set on the settings panel of the corresponding Face Recognition Server object – see Configuring the Face Recognition Server object) and saving of photos will be performed.

...

1. To enable the pixelating function, set the Pixelate area checkbox (5).

2. Set the Grain size cursor in position corresponding to the pixelation grain size in pixels (6).

...

If it is necessary to convert the color video image to black and white image to generate the vectors by the black-and-white frames, then uncheck the Process color video checkbox (10).

By default the Face detection tool processes a video with the resolution set for the Camera parent object.  To process a video with 320x240 pixels resolution, set the Process video in low resolution checkbox (11).

Set the minimum and maximum width and height of the face on the video image in pixels in the corresponding fields of the Face size, pixels group (12).

Set the Zoom slider to the position corresponding to the required scaling of a captured face in the frame for recording (13). The current scale value is displayed in the field above the slider and ranges from 1 (only the captured face is recorded) to 5 (the whole frame is recorded).

To save the changes click the Apply button (14).
