How to normalize photo in DU?

Hi everyone,

I would like to get data from the ID Card, but sometimes the photo is not normal.

  • Some photo has a background
  • Some photo already cropped, so it didn’t have a background
  • Some photo is scanned using a scanner, there will be a white background.
  • Some photo is captured from mobile phone
  • Some photo is grayscaled.

Here is example picture

  • Anyone can suggest how to normalize the photo before I feed the picture to DU Framework?
  • If it doesn’t need to be normalized, what is the best DU extractor for this use case?

I believe ID card is a common use case for OCR and it will help all people that starting learn DU.

Kind Regards
Alex

Hi @alexologica,
If you need to “normalize” photo you can search in Package Management in Studio for some custom activities for image operation.

What is the best practice from UiPath for this situation? Does DU capable to handle this situation?

It’s hard to say what’s the best practice in such cases. All depends of the situation. Regarding framework. Each framework is ok. You just need to built you processing part to fit the requirements of particular framework.
