In order for a barcode to be properly scanned using Vision Builder AI, it is important that the barcode is printed on a flat surface without any textures so that the lines can be easily detected. In case of the paper being textured we can try and use some image processing techniques in order to possibly overcome the issue.

The key to removing textures/repeating patterns from an image is by using an FFT filter on the image. Use this steps to open the FFT filter function:
  1. Navigate to Enhance Images Tab
  2. Click on the Vision Assistant Step
  3. Navigate to the Grayscale step
  4. Click on the FFT Filter step
  5. Adjust the parameters until optimal results are achieved
