How to make tesseract recognize number 0 with open top right corner which is included in EU plates?

I have this character image:

enter image description here

This Image of 0 is similar to ones found in some eu plate cars. for example this image:

enter image description here

How to make tesseract (if possible) to recognise the 0 in the image as 0 in python or any other language? Currently on its on it is recognize it as u. Of-course if I croped the 0 and the 2 together is recognises them as digits (0 2) as there is nothing else but I want to recognize every single character where any general plate can have any number of characters in any order. Do I need to retrain tesseract? Thank you.

Solution

  • I used the trained font (tesseract) from this git repository:

    https://github.com/openalpr/openalpr/tree/master/runtime_data/ocr/tessdata

    They have trained data for various car plates and use can use any of them for your plate OCR.
