Simple captcha solving? - s3rEnity - Jun 20, 2019

Hey, trying to solve captchas similar to the following:

I've tried using AForge.NET and tesseract together but it seems that the gradient in the background is an issue. Any tips?

This is the code I've followed: Windows Solving Captchas with C#, AForge.NET and Tesseract sample in C# for Visual Studio 2015

I'm guessing there's too much "noise" for the OCR to detect. I would have it crop out the majority of the image so you'll have as little white gradient as possible when it inverts the image.   If that doesn't work you may have to have it detect pixel color and manually change to a uniform color before inverting which shouldn't be hard to do with a simple loop and if statement.

The README says otherwise.

I mean 2captcha could solve 1000 of these for a maximum of 60cents.
