Recognition Server

7. recognition server (1):

   1. External capture is NOT selected, and the detection is NOT added to any channel of the Face
Recognition Server channels
8. 1. recognition server. In this case,
only capturing of

10. 1. are captured by Axxon PSIM face capturing, and
generation of vectors is not performed
11. 1. vectors aren't generated. This option

12. 1. isn't used in Face PSIM.

15. 1. recognition server. In this case,
capturing and saving of

)

    Info
    title Note

Proper configuring of the face recognition server selected as external capture is performed with the help of the Cfgedit.exe utility (

36. When you use Cognitec face recognizer, you can fine-tune the Face recognition server that you select as an external capture using the Cfgedit.exe utilit (for the detailed information about this utility, see

in the

37. Cfgedit.exe utility for configuring the Cognitec face recognizer

section

38. ).

39. The Maximum performance mode is enabled by default (2). This mode allows improving the quality of face capture and recognition by using all available processor cores and increasing the RAM consumption.

    Info
    title Note
    When you use VisionLabs face recognizer, the Maximum performance checkbox is cleared automatically, and the setting becomes inactive when you select the Face recognition server in the previous step. This is due to the feature of this recognizer.

56. Set the Scaling and selection slider (5) to the position corresponding to the required scale of the captured face in the frame for recording and highlighting the face with a dynamic frame. 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).
57. In the Processing speed, fps field (6), specify how many
fps
58. FPS from the video stream are processed by the Face detection program module. This parameter is necessary for reducing the load on the
Server
59. server.

60. If it is necessary

to convert the

image to

62. image to a black-and-white image to generate the vectors by the black-and-white frames, then

uncheck the

    Note
    title Attention!
    Generation of vectors by black-and-white frames is supported by

Tevian

64. the VA and VideoIntellect 1.1 face recognition modules only. It reduces the CPU load, insignificantly affecting the face capture and recognition quality.

65. By default, the Face

68. parent object. To process a video with 320x240

pixels

69. pixel resolution, set the Process low resolution video checkbox (8).

    Info

    Enabling this option reduces the load

of

70. on the

Server’s

71. server processor, but the probability of face capture also reduces.

80. 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 (9).

    Info
    title Note
    If the specified minimum dimensions differ significantly from the actual ones, then the faces

will not be captured.

81. won't be recognized by the detector. For example, if the video contains large faces (15-30%), then if you set the minimum size to 5%

,

82. and the maximum size to 80%,

the

85. faces will be

87. Thus, if the

detection tool

88. detector is configured to capture small faces, then it cannot detect large ones, and vice versa.

Info

89. If all parameters of face

sizes

90. size are set to 0, the Face Detection

tool

91. module uses similar parameters

set on the Face Recognition Server object settings panel

92. specified on the settings panel of the Face recognition server object (see Configuring the

Info

When using Visionlabs

95. If you use the VisionLabs face recognition module, the minimum and maximum values for all face

detection tools should

96. detectors must be the same, as the values are set for the entire software module.

97. From the Select GPU drop-down list (10), select a video card for recognition for the VA and VisionLabs modules. The Use GPU checkbox must be set on the settings panel of the Face recognition server object (see Configuring the recognition parameters of captured faces).
    

    Note
    title Attention!
    All GPUs with Pascal architecture are not supported by the VA module; if you select such a graphics card, faces will not be recognized.
