The following table provides descriptions of the parameters for configuring the Face Detection.
№ | Parameter | Method for entering the parameter value | Parameter description | Symbols used | Default value | Value range |
|---|---|---|---|---|---|---|
1 | Number | Automatic | Identification number of the Face Detection object in the system | Sequence of numbers | - | Depends on the number of Face Detection objects in the system |
2 | Name | Enter the value into the field | Name of the Face Detection object in the system | Latin, Cyrillic and service characters | Face Detection | A line containing a sequence of any symbols (letters, digits, service characters), regardless of the register |
3 | Disable | Checkbox | Sets the status (on or off) of the Face Detection object in the system | Boolean type | No | Yes – the Face Detection object is disconnected and is not in use |
4 | Camera | Select the value from the list | Assigns the parent Camera object to a particular Face Detection object | Name of the Camera objects registered in the system | Name of parent camera | Depends on the number of Camera objects in the system |
| Search area border % group | ||||||
| 5 | Left, Right, Upper and Lower fields | Enter the value into the field | Sets the face search area border on the video image by specifying the required values in percent of the corrresponding frame sides | The percentage of the left, right, top and bottom sides of the frame | Left = 0 Right = 100 Upper = 0 Lower =100 | 0 to 100 |
| Note. Setting the face search area border is avaiable only if the Tevian face recognition module is used. | ||||||
| External capture group | ||||||
6 | External capture | Select the value from the list | Selects the Face recognition server object | Name of the Face recognition server objects registered in the system | No | Depends on the number of Face recognition server objects in the system |
| 7 | Maximum performance | Checkbox | Enables maximum performance mode | Boolean type | Yes | Yes – the maximum quality of face capture and recognition is provided by using all available processor cores and increasing the consumed RAM. No – normal resources consumption, faces can be missed while capturing. |
| Face capture area pixelation group | ||||||
8 | Pixelate area | Checkbox | Enables the pixelation function for the area of video image in which the face was recognized | Boolean type | No | Yes – face capture area is pixelated. |
9 | Grain size | Move slider bar to position | Sets the grain size of face capture area pixelation | Sequence of numbers | 5 | From 5 to 15 |
Settings group | ||||||
10 | Frame rate, fps | Enter the value into the field | Enters the number of frames per second processed by the Face Detection module. This parameter is used to decrease the server load | Frames/sec | - | From 1 to the frequency of frames allocated for processing the video signal of each specific video camera |
11 | Frame color if face size more than, % | Enter the value into the field | Sets the captured face size at which the face requires a dynamic border | % of the video surveillance camera window area | - | From 1 to 100 |
12 | Color | Double-click | Selects the color of the dynamic border (via the standard Windows dialog box) | - | - | - |
| 13 | Process color video | Checkbox | Enable/disable the convertion of the color video image to black and white image to generate the vectors by the black-and-white frames. | Boolean type | Yes | Yes – when adding faces to the reference faces database, vectors are generated by color images. No – when adding faces to the reference faces database, vectors are generated by black-and-white images. |
| 14 | Process video in low resolution | Checkbox | Activates the option to have the Face Detection module process video images in the 320x240 pixel resolution. | Boolean type | No | Yes – video image is processed in the 320x240 pixel resolution No – video image is processed in the resolution set by the parent Camera object |
| Face size, pixels group | ||||||
| 15 | Min.width, Min.height, Max.width and Max.height fields | Enter the value into the field | Sets the minimum and maximum width and height of the face on the video image in pixels | Natural number series with zero included | Min.width =80 Min.height =80 Max.width = 600 Max.height =600 | From 0 and more |
Zooming face capture area group | ||||||
16 | Zoom | Move slider bar to position | Sets the scale of the captured face image within the frame to be recorded | - | 1.5 | From 1 to 5 |
