Configuring the neurotracker track counter

To configure the neurotracker track counter, do the following:

1. Go to the settings panel of the Track counter object, which is created on the basis of the Neurotracker object.
   
2. Specify the surveillance area on the video image in which the neurocounter counts objects:
   1. Click the Settings button (1). As a result, the Detection settings window opens.
      
   2. Click the Stop video button (1) to capture a frame of the video image.

   3. Click the Area of interest button (2) and specify the area within which the neurotracker counts objects (3).

      Note

      To delete the selected area, click the button (4).

   4. Click the OK button (5).
3. If you don't set the Generate event only when the number is changed checkbox (4), then from the Counter period drop-down list (2), select the counter period time unit: seconds, minutes, hours, days. Then in the field (3), enter the time through which the event containing the total number of objects recorded for the given time period is generated.
   The allowable range of values for the time units: seconds, minutes, hours—from 1 to 100, days—from 1 to 20.
   

   Note

   If the entered value exceeds the allowable range, then after you click the Apply button, the maximum value is set automatically.

4. Set the Generate event only when the number is changed checkbox (4) if you want to generate events only when changing the number of recorded objects.

   Note

   If you set this checkbox, the Counter period field becomes inactive, and the specified value of the counter period is ignored.

5. If objects are lost during the track counter operation, then for more accurate counting, set the Set number of frames for counting checkbox (5), and in the field (6), enter the number of frames that are analyzed to calculate the average object number.

   Note

   This feature works only if you set the Generate event only when the number is changed checkbox.

   The value of the number of frames for counting is selected experimentally depending on the neural network used. Recommended values are: 3, 5, 7, 9.

6. Click the Apply button (7).

Configuring the neurotracker track counter is complete.
