• Result
If the average brightness value inside the ROI is above the set threshold, the result will be
positive (green colour indicator and ROI edge) if it is below the threshold, the result will be
negative (red colour indicator and ROI edge)
• Example
We would like to add the "Brightness" test to the current inspection to check for the presence of
magnetic strips on badges.
Select "Brightness" from the Controls menu and press SET.
First of all let's resize and position the ROI along the magnetic strip: Follow the instructions
provided earlier during this procedure.
Let's now invert the grey colour scale. This means the magnetic strip will appear white, and the
rest of the badge will be black. To do this, enter the camera setting control panel and enable the
Negative option.
