### Monitoring Tab

In the fourth tab of the Visual Quality Control software, the visualization of the monitoring process is performed. 


As soon as the request to the monitoring service arrives, the monitoring service obtains the image, processes it and during the processing it calls the visualization service to demonstrate the results (intermediate and final) to the user.

By default, the initial images are stored in the folder, which is defined in *settings.json* under the field __monitoring: save__.
If the check box "Do Not save Images " is checked, no images will be saved.

To start the monitoring service:

    rosrun templatetester monitoring_node_server

To call the monitoring service:

    rosservice call /templatetester monitoring_node_server parameters
    
Similarly to the Testing Tab, the template, ROI, and result images will be shown.
