6. There are several variations of the face detection operation depending on the setting of the external capture and Face recognition server (1):

   1. External capture is NOT selected, and the detection is NOT added to any channel of the Face recognition server
channels
7. 1. . In this case, faces are captured by Axxon PSIM face capturing, and vectors aren't generated. This option isn't used in Face PSIM.
   2. External capture is NOT selected, but the detection is added to
any

channels
9. 1. . In this case, the photos of captured faces are captured and saved

    2. External capture is selected, but the detection is NOT added to any channel of the Face recognition server

Proper configuring of the Face recognition server selected as external capture is performed with the help of the Cfgedit.exe utility (for the detailed information about this utility, see Cfgedit.exe utility for configuring the Cognitec face recognizer)

    Info

    When you use VL recognition module 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.

29. Set the border of the face search area

if

39. 1. for the

VA or VideoIntellect 1.1 face recognition modules are used

40. 1. Recognition module VA and Recognition module VI face recognition modules.

41. 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).
42. In the Processing speed, fps field (6), specify how many FPS from the video stream are processed by the Face detection program module. This parameter is necessary for reducing the load on the
Server
43. server.

44. If it is necessary to convert the color video image to a black-and-white image to generate the vectors by the black-and-white frames, then clear the Process color video checkbox (7).

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

VA and VideoIntellect 1.1 face recognition modules only

45. the Recognition module VA and Recognition module VI only. It reduces the CPU load, insignificantly affecting the face capture and recognition quality.

46. By default, the Face

detection tool

47. detector processes a video with the resolution set for the Camera

 parent

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

pixels

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

    Info
    title Note
    Enabling this option reduces the load

of

50. on the

Server’s

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

NotetitleAttention!

52. The Process low resolution video setting

is not relevant in case,

53. isn't relevant when a high resolution is set for the Camera parent object. Also, this

settings

54. setting isn't used if the Recognition module VA or

VideoIntellect 1.1 module is applied for face capture

55. Recognition module VI module is used to capture a face.

56. 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.

57. 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%

,

58. and the maximum size to 80%,

 then

59. then the faces

will not

60. won't be detected. However, if you specify a minimum size of 12% and a maximum size of 80%,

the

61. faces will be

captured

62. detected.

63. Thus, if the

detection tool

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

InfotitleNote

65. If all parameters of face

sizes

66. size are set to 0, the Face Detection

tool

67. module uses similar parameters

set on the

When using VisionLabs face

72. If you use the VL recognition module, the minimum and maximum values for all face

detection tools should

74. From the Select GPU drop-down list (10), select a video card for recognition for the Recognition module VA and VL recognition module. 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 Recognition module VA; if you select such a graphics card, faces will not be recognized.
