Converting colored background and colored characters to text with the Tesseract library

[Emre Batu]

  Hello everyone. I am using the Tesseract library in a C# application to analyze images. However, the image I want to convert to text contains colored characters and a colored background. As a result, the output is not accurate. How can I convert this image to text correctly? Thank you.

Captcha was created to fool OCR.

The link generating the mentioned captcha is as follows: https://medeczane.sgk.gov.tr/eczane/SayiUretenImageYeniServlet

Do you have any idea how I can convert the numbers generated on this link into text? I have tried some C# code that changes the background color to white and the text to black. It is partially successful, but it does not achieve the desired result completely.
