You can configure the Sweethearting at checkout detection program module on the settings panel of the the Sweethearting at checkout detection object created on the basis of the Camera object on the Hardware tab of the System settings dialog window.

Basic settings of the

...

detector

To configure the Sweethearting at checkout detection program module, do the following:

1. Go to the settings panel of the Sweethearting at checkout detection object.
   
2. By default, the standard (default) neural networks of hand and goods recognition in the frame are initialized according to the device selected at step 3. You must not select manually the standard neural networks for the different processor types since it is performed automatically. If you want to use custom neural networks, click the the  button to the left right of the Tracking model (Hand recognition in the frame) and Tracking model (Goods recognition in the frame) fields, and in the standard Windows Explorer window that opens, specify the file of the corresponding neural network.
3. From the Device drop-down list, select the device on which the neural network will operate: CPU, one of the NVIDIA GPUs, or one of the Intel GPUs. Auto (default)—the device is selected automatically:  The NVIDIA GPU gets the highest priority, followed by the Intel GPU, then the CPU.
   

   Note
   title Attention!
   We recommend using the GPU. It can take several minutes to launch the algorithm on the NVIDIA GPU after you apply the settings. You can use caching to speed up future launches (see Configuring the speedup of neural analytics launch on GPU).

Selecting area of interest

1. Click the Settings button. The Detection settings window opens.
   
2. Go to the On the Select area tab and , click the the Stop video button to pause the playback and capture a video framethe frame of the video image.
3. Click the Area of interest button to specify an the area of interest. The button is highlighted in blue color.
   
4. On the captured video frame, use sequentially set the mouse to set anchor points of the area where using the mouse in which objects are detected. The rest , and the remaining part of the frame is grayed outdarkened. The selected This area must meet the requirements described in in the Camera requirements for the Sweethearting at checkout detection module section. If you don't specify the area of interest, the entire frame is analyzed.
   

   Info
   title Note
   You can add only one area. If you try to add a the second area, the first area will be is deleted. To delete an area, click the Image Modified button to the right of the Area of interest button.

Configuring the

detector parameters

1. Go to the Parameters tab of the Detection settings window.
   
    

2. In the Detection sensitivity [0.0, 1.0] field, specify the detection sensitivity in the range from 0.0 to 1.0. The default value is 0.65.

   Info
   title Note
   The detection sensitivity value is selected experimentally. The lower the sensitivity, the greater the probability of false positives. The higher the sensitivity, the less chance of false alarms, however, some useful tracks can be skipped.

3. In the Frames processed per second (second [0.016-, 100)] field, specify the number of frames per second that the detection tool detector processes in the range from 0.016 до to 100. The default value is 12.

4. Click the OK button to save the changes and return to the settings panel of the Sweethearting at checkout detection object.

   Info
   title Note
   To return to the settings panel of the Sweethearting at checkout detection object without saving the changes, click the the Cancel button.

5. Click the Apply button to save the changes.
