4. In ScanMultipleStripes filter set the following parameters:

   • inStripeScanParams.StripePolarity to value Dark because caps are darker than the background,

   • inStripeScanParams.MinStripeWidth to 45 because the width is approximately equal to this value (it can be measured with a ruler from the top toolbar).

5. Expand outStripes output of ScanMultipleStripes filter. Choose Count property output.

6. Add a new formula. Connect outStripes.Count to it as inBottleCount. Add another input - inExpectedCount set to 4. Create an output outCountOK:

   outCountOK = inBottleCount == inExpectedCount
